10.1各方向性質鋼板產品屬於平板，以軋延扁鋼胚來製造，軋延方向（縱向）的性質一般比橫向的性質為佳。但由於

扁鋼胚以連續鑄造產製，在冷却過程心部有偏析現象，對於厚度方向受到拉伸應力的用途，應視需要

要求厚度方向之性質，例如厚度向斷面縮率。

10.2加工方式與品質特性鋼板產品最常見的加工方式為切割、彎曲及銲接；其中銲接為最主要的加工方式，幾乎所有鋼板都需

要銲接。鋼板的使用除有尺寸許可差及表面品質要求外，內部品質為滿足各種用途，需具備相對應的

品質特性，例如強度、韌性、彎曲性、銲接性、耐蝕性、切割性、耐震性⋯等。因此，於設計階段即

必須仔細規劃，考慮後續相關的加工製程，以防止失效。

10.3切割的影響由於剪切會造成切斷面上微裂、毛邊，並產生硬化層，容易造成對後續加工性不利的端面裂縫。對此，

可以採取去除毛邊附予斷面圓角，或以火嘴加熱端面、退火等方法來防止裂縫。

焰切斷面由於附近會產生淬火效應，會比其他部位硬，此種硬化性會隨著碳當量的增高而增大，如能

在焰切前後稍微加熱軟化，將有利於加工性。

10.4銲接性銲接部位包括熔融區（又稱銲接金屬（WM））與熱影響區（HAZ），熔融區變成一種鑄造組織，而

熱影響區因淬火效果，硬度一般較母材高。熱影響區一旦硬化，延性隨之下降，在銲接或使用中會變

得容易引裂，因此必須確定材質及銲接條件，使熱影響區的最高硬度儘可能降低。由於最高硬度一般

與碳含量成正比，因此鋼板產品設計會考量所添加合金的效應所換算而成的「碳當量」，並儘量最小

化，以提升銲接性。

碳當量 Ceq（%）＝ C＋Mn/6＋（Cr+Mo+V）/5＋（Ni+Cu）/15

鋼中含有鎳 (Ni)、鉻 (Cr)、鉬 (Mo)、銅 (Cu)、釩 (V)、鈮 (Nb)等之合金元素，在銲接時的熱

影響區，容易形成硬脆的組織，因而易發生熱影響區的延性降低以及低溫龜裂等問題，在施工時必需

十分的注意。

客戶使用注意事項


43

低溫龜裂是在銲接後，經過一段時間以後所發生的龜裂，包括銲道下方裂紋 (underbead crack)、根部裂紋 (root

crack)、銲趾裂紋 (toe crack)等，但這類低溫龜裂的原因有：銲接熱影響區的延性、銲接金屬的擴散氫量、拘

束度以及鋼材之硬化性能。以鋼材製造者而言，在高強度鋼板的開發過程中，為能生產出耐銲接龜裂性優良的鋼，

必須把握鋼材的化學成分與銲接冷裂敏感指數（PCM）之關係。

PCM是將「與產生低溫龜裂有關的鋼材化學成分」做定量評價其影響之數值，此數值愈低的鋼材，其銲接龜裂敏

感性也愈小，在銲接施工時，可降低預熱溫度。

銲接冷裂敏感指數 PCM（%）＝ C+ Si/30+ Mn/20+ Cu/20+ Ni/60+ Cr/20+ Mo/15+ V/10+ 5B

10.5彎曲性彎曲加工的半徑不能超過鋼板規格的最小彎曲半徑，此最小彎曲半徑決定於板厚及材質。最小彎曲半徑愈小，

則彎曲性愈佳。至於板厚的影響，厚度愈厚則愈難加工，最小彎曲半徑也會變大。

鋼板由於縱向性質優於橫向性質，因此彎曲方向平行軋延方向時，材料較能承受加工應變；反之，彎曲方向垂

直軋延方向時，容易裂。此現象在放樣階段即應納入考慮，以避免彎裂。此外，剪切面之破斷面（毛邊）應置

於彎曲內側，以避免因拉伸應力而致裂。

10.6超音波檢測(1)本公司由於使用連鑄扁鋼胚軋製鋼板，扁鋼胚最厚 270mm，但為滿足客戶需求，儘量擴展鋼板厚度範圍，

惟限於軋延比及使用安全性的考量，客戶應考慮其用途，加做超音波檢測。

(2)超音波檢測的標準如下：

(a)ASTM A435及 A578：主要在檢測夾層型缺陷。A578分為 Level A、B、C，A與 A435相同 (單一

缺陷管制不大於 3inch或 1/2板厚之直徑之圓 )；B為合併鄰近小缺陷為一；C最嚴，原 A之 3 inch

改為 1 inch。

(b)JIS G0801及G0901：G0801用於壓力容器，分 Type SG、AC、AL，Class X、Y。G0901用於

建築結構，分 Class X、Y。主要檢測夾層及點狀缺陷，其中G0801又嚴於G0901。

China Steel Corporation (CSC) is an integrated

steel producer that has produced steel plates

since the commencement of its plate mill. Through

developments and improvements over the years,

CSC's comprehensive steel plate grades have

fulfi lled industrial requirements demanded by general

structure and building applications such as earthquake

resistance, weather resistance, corrosion resistance,

fire resistance, bridge and welding, as well as other

uses like construction of ships, pressure vessels, line

pipes, HIC resistance, laser-cutting, etc.

Much emphasis has placed on product safety

standards. As surrounding conditions change, the

quality and reliability of the steel become increasingly

important. If quality fails, accidents and severe

consequences may result. Therefore, besides selecting

the proper type of steel plate, it is also crucial for a steel

producer to adopt proper design, process equipment,

production conditions and quality control demanded by

customer's requirements and specifi cations in order to

ensure quality and stability.

CSC's steel plates have been approved by certifi cations

such as ABS, BV, CR, CCS, DNV, GL, KR, LR, NK, ISO

9001, ISO/TS 16949, JIS MARK. They also conform to

the regulations of QC080000, RoHS and REACH. The

approvals and qualifications are testament to CSC's

commitment to reliable and superior products, thus

providing its clients a peace of mind.

The vision of CSC's customer services is to gain

Plates are fi nally air cooled as they are transferred across a cooling bed. In special cases, stacking of plates to reduce the cooling rate is employed.

Ultrasonic Testing is a form of quality assurance used for ensuring the strength and quality of rolled steel plate.

Paint printing can be done on the surface of steel plate according to the requirements of customers and standards.

As well as cutting discrete plates to their ordered sizes. The shear-line also extracts test samples which are used to certify the plate properties.

The plates be treated by roller normalizing furnace, which can normalize, temper, anneal and stress-relief.

Slabs are heated a temperature in a typical range from 1150 to 1270 ℃ . Reheating reduces the deformation strength of slabs sufficiently to allow it to be rolled, and ensure that all alloy elements are in solid solution.

The rolling process for a plate thus has to achieve the correct dimensions. The device(HAGC,WRB,AWC) is used to obtain excellent dimensional accuracy and uniformity.

The addition of an edger and its integrated width control automation package gives more accurate control of the product width and signifi cantly reduces width variations.

ACC equipments can be used to realize TMCP process and improve the properties of steel plates. Thermo-mechanical control process(TMCP) is a micro-structural control technique combining controlled rolling and cooling.

Leveller is a stress relief process carried out through low and controlled elongation in a multi-roller machine, the plate surface undergoing a series of reverse bends.

HAGC (Hydraulic Automatic Gauge Control ):

Automatic gauge control(AGC)is a closed loop control function designed to regulate thickness at the exit of the rolling mill stand to increase the thickness accuracy. To make sure that the fl at products rolled in the mill are of required uniform thickness within the required tolerance.

AWC (Automatic Width Control):

Automatic width control (AWC) can be applied at each edger to provide in-bar width control to increase the width accuracy by adjusting the roll gap. The addition of an edger and its integrated width control automation package gives more accurate control of the product width and signifi cantly reduces width variations.

WRB (Work Roll Bending System):

The crowned roller will only compensate for one set of condition, specifically the material, temperature, and amount of deformation. Work roll bending involves using hydraulic cylinders at the ends of the rolls to counteract roll defl ection. To make sure the fl atness coming into the mill will be preserved at the exit of the mill.

CSAC (China Steel Accelerated Cooling):

Thermo-mechanical control process (TMCP) is a micro-structural control technique combining controlled rolling and cooling. TMCP is used to obtain excellent properties for steel plants, such as high strength, excellent toughness, and excellent weld-ability.

10.1 Orientation Feature

Plate products are produced from slabs through rolling process. In general, the properties of plate on rolling

direction (longitudinal) are better than those on transverse direction. In addition, the applications, which stress is

applied on thickness direction and the effect of middle thickness position of plate due to the center segregation

of slabs, shall be considered. The properties on thickness direction shall be also asked to announce and verify

if necessary.

10.2 Post-Processes and Quality Requirements

The ways of processing for plate products are mostly often seen in cutting, bending and welding, among which

welding is specially the most major way of processing since almost all applications of steel plates need to have

the post-process for welding. The use of steel plates, in addition to the requirements for specifi cation tolerance

and surface quality, the inner quality for satisfying various uses needs to have the corresponding quality

properties, such as strength, toughness, corrosion resistance, weldability etc. Therefore, it should plan carefully

in the early stage of material design according to the end-uses and consider the subsequent corresponding

processes to avoid unexpected failures.

10.3 The Infl uences of Cutting

Since shear-cutting produces some unfavorable features such as micro cracks, burrs and hardened layer on

the cutting surface, it is easy to result in the end-surface cracks that are detrimental to following processes. The

effective methods to prevent the occurring of end-surface cracks are removing of burrs, making of rounded

corners or heat annealing.

Flame-cutting will harden the cutting surface by the quenching effect which is positively correlative to the

carbon equivalent. Mild heating to the cutting region before and after fl ame-cutting is helpful to the subsequent

processes.

10.4 Weldability

Welding area includes fusion zone (i.e. the weld metal) and heat affected zone (HAZ). The fusion zone

forms casting texture while the HAZ turns to a hardened area after welding. Due to quenching effect, HAZ is

characterized by its low elongation and could be a crack source during welding or using. Hence, the material

properties and welding conditions have to be confi rmed so that the highest hardness in heat affected zone can

be possibly reduced. Since the highest hardness is generally a direct proportion with the carbon content, the

hardened area alloy additions (as carbon equivalent) can be considered and adjusted from the early stage of

material design in order to improve the weldability and reduce the detrimental effects of HAZ.

The carbon equivalent can be estimated by following equation:

Ceq(%) = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15Steel grades that contains Ni, Cr, Mo, Cu, V and Nb in the composition need to be treated carefully during welding

because the material is easy to form a HAZ with very hard textures and result in such problems as low elongation and low-

temperature cracks.

Low-temperature crack happens after a period of time from the welding, including underbead crack, root crack and toe

crack, etc. The causes of low-temperature crack include the elongation of HAZ, the diffusion of hydrogen in weld metal, and

the restraint and hardenability of material.

PCM, the low-temperature crack sensitivity, is a quantitative index to monitor the correlation between chemical

composition and low-temperature crack occurrence, which can be calculated as below:

PCM（%）＝ C+ Si/30+ Mn/20+ Cu/20+ Ni/60+ Cr/20+ Mo/15+ V/10+ 5BThe lower PCM value, the lower risk of crack of materials is. It may reduce preheating temperature when doing the welding.

PCM is a very important property to the steel maker developing high strength steels, and it have to be properly handled for

the production of steels with excellent weldability and crack resistance.

10.5 Bendability

The bending radius applied on a steel plate shall not be smaller than the minimum value given by specifi cation. The degree

of minimum bending radius depends on the thickness and materials of steel plates. The smaller minimum bending radius,

the better bendability of steel plates is. As for the infl uences of thickness of steel plates, the thicker, the more diffi cult

processing is, and the larger minimum bending radius becomes, too.

Because the effect of rolling steel plates with longitudinal direction for bending work is better than that with the transverse

direction, when the bending direction is toward parallel direction of rolling, the materials can bear more strains. In reverse,

it is easy to crack if the bending direction is vertical direction of rolling. These factors should be regarded at sampling and

planning stage for preventing bending work from cracks. Furthermore, burrs of cutting surface are supposed to be in the

inner radius of bending since they are crack inducers under tension stress.

10.6 Ultrasonic Test

(1) Since CSC uses continuous casting slabs to roll steel plates, the maximum thickness of slabs is 270 mm. The

maximum thickness of plate would be extended as possible to meet requirments of customers. And for the rolling ratio

and safty considerations, customers should consider doing the UT examination.

(2) Adoptable ultrasonic test standards are listed as follows:

(a) ASTM A435 and A578: The ultrasonic tests that focus on inner layer type defect detection. Test and acceptance

criteria of A578 are divided into 3 levels of A, B and C. Level A is the same with A435 that single defective spot shall

not be larger than 3 inch or the circle area of the diameter of 1/2 thickness. Level B is altered from level A that nearby

small defects will be involved into the calculation of defect size. Level C is the strictest that the acceptable single

maximum defect size shall not be larger than 1 inch.

(b) JIS G0801 and G0901: G0801 is designed for pressure vessels and is divided into 3 types of SG、AC、AL and

class X、Y. G0901 is designed for building structures and is divided into 2 types of X and Y. Both standards focus on

the detection of inner layers and defect spots that the criteria of G0801 are stricter than that of G0901.
