Wrought Iron resists corrosion in two ways. First, the number of slag fibers in theWroug-ht Iron is so great that they act as a barrier against the progress of corrosion andforce it to spread over the surface of the metal rather than to pit. Thus the corrosion isconfined to a film on the surface of the metal. Secondly, the ability of Wrought Iron to develop a dense, uniform and adherent film effectively protects the underlying metal from

any further corrosion. Because of its resistanee to corrosion, Wrought Iron is often usedin Marine applications and situations where the metal is exposed to the elements.Resistance t Heat

Hand Puddled Wrought Iron stands up under hig-h temperatures and does not wasteor burn away under repeated beatings. Ordinary steel begins to melt at 2100F. WroughtIron does not begin to melt before 2800F - a difference of 700 degrees.

Wrought Iron's ability to stand up under high temperatures results from its lowcarbon content about .02 to .04 per cent.

OW ULST R WROUGHT IRON IS M DEULSTER Hand Puddled Wrought Iron is a quality product. Hand-puddl ing , as the

term implies, is largely a manual operation and requires a large amount of skilled labor,with a relatively small output per man. This makes the manufacture costly, but it insuresqualities which no other method or process equals. The important advantage of Hand-puddling over other processes is that it effects a minute and uniform distribution of theslag fibers throughout the body of the metal. Besides the skilled supervision and the closecontrol of raw materials that goes into the making of ULSTER Iron, there is an integrityof workmanship handed down through the years which guarantees quality beyond anyspecification's description.

In the manufacture of ULSTER Ha nd Puddled Wrought Iron a charge of pig iron ismelted in the shallow hearth of a Reverberatory Furnace. Impurities are oxidized whilethe metal is molten. This process is stimulated by the addition of iron oxide and the rapidagitation of the molten metal by the puddler, who rabbles the bath with a long iron hook.The oxidizing reaction effects an almost complete elimination of the carbon, silicon, phosphorous, sulphur and manganese originally present in the pig iron.

Owing to the fact that the melting point of the metal rises with the decreasing content of impurities, the purification finally reaches the stage where the temperature in thefurnace is not sufficient to keep the metal molten. The metallic iron then assumes a pastystate immersed in the surrounding slag. The iron is then gathered into balls by the puddler, and these are commonly known as puddle balls .

The puddle ball is then placed in the squeezer which squeezes and kneads themass of plastic metal and slag, causing t he excess slag to be squeezed out. The massemerges from the squeezer in the form of a rough, elongated bloom of correct size to bepassed through the bar mill.

, The material emerges f rom the bar mill in the form of rough bars called puddlebars .

Wrought Ironis easy to forgeby any of thecommon methods. The heat range atwhich forging can be done is quite wide but two extremes should be avoided. At highheats the s lag content of iron becom es liquid andthe laminatedstructure ofthe i ronmay allow th es lag to be voided and fo rmcracks. For th is r eason it is sugges ted that\vhite hot heats be avo ided. On the other hand, at a dull red he at ac ritical temperature isreached at whichpoint i ron becomes red sho rt and fractures when worked . For U L S T E R
