To make tomorrow’s cars even lighter ThyssenKrupp Steel Europe is taking a new approach to hot forming with the composite material TRIBOND®. Unlike monolithic materials, TRIBOND® makes it possible to combine conflicting properties in one product: maximum ductility and high strength – for tailored property profiles in auto production.

High ductility

TRIBOND® steels allow unprecedented bending angles of up to 135° in hot forming.

High potential for weight reduction

Particularly in crash-relevant parts the 10 -15 percent weight reduction potential of TRIBOND® opens up new design and manufacturing possibilities through the material’s high strength compared with conventional cold forming solutions.

Ease of processing

TRIBOND® steels are ideal for structural parts requiring high energy absorption capacity and are just as easy to process as the standard material MBW® 1500+AS.

THREE ADVANTAGES, ONE INGENIOUS SOLUTION

MATERIAL WITH NEW POTENTIAL

The performance data of the new TRIBOND® materials show how conflicting properties can be combined to targeted effect. With the new steel composites TRIBOND® 1200 and TRIBOND® 1400 you

have two materials that open up new and promising applications for the hot forming of body parts without the need to change your standard processes.

TRIBOND®, the new composite for hot forming, combines properties

previously regarded as incompatible: ultrahigh strength coupled with

high energy absorption through controlled axial deformation. It allows

up to two and a half times higher bending angles compared with the

standard material MBW® 1500+AS.

Hot forming made easy.

Materials for hot forming offer potential for cost and weight reduction in auto production but require proven expertise in manufacturing and processing. As an international technology partner to the auto industry we can offer service packages tailored to specific needs that benefit our customers in many different ways:

• Advice on choice of materials, coating systems and processes • Expertise in microstructure and layer design and recommendations

for heating and cooling conditions• Analysis of customer-specific production processes to secure

volume production • Metallographic assessment of material properties, process

parameters and their interactions • Thermomechanically coupled FEM analysis support for part

feasibility and part properties

Together these services add up to a comprehensive understanding of materials and open up attractive possibilities for our customers in developing new solutions.
