Mazda develops world’s first cold-stamped parts using 1,310 MPA-class high-strength steel

Mazda Motor Corporation, working separately with Nippon Steel & Sumitomo Metal Corporation and JFE Steel Corporation, has developed the world’s first cold-stamped vehicle body parts made from 1,310 MPa-class high-strength steel.1 The parts are used in Mazda’s new-generation Skyactiv-Vehicle Architecture, which will underpin upcoming models starting from the all-new Mazda3.To get more news about Stamping steel parts, you can visit official website.

High-strength steel enables automakers to make parts from thinner sheet metal while retaining the necessary yield strength. This results in a lighter vehicle body, which contributes to improved handling stability and fuel economy. A strong body is also essential to ensure crash safety performance, and the application of higher-strength steel has been widely anticipated.

Until now, cold-stamping of vehicle body structural members has only been possible with 1,180 MPa or lower-classed steel, due to the material’s formability and the difficulty of ensuring dimensional accuracy after processing. Working in collaboration with the above-mentioned companies, however, Mazda has found an appropriate set of processing conditions that make the process possible with 1,310 MPa-class high-strength steel.

The all-new Mazda3 uses 1,310 MPa-class high-strength steel for the front pillar inner, the roof rail inner, the hinge pillar reinforcement, the roof rail reinforcement, the No. 2 crossmember and the side sill inner reinforcement, saving about 3 kilograms over the same parts in the previous model.

We at Manitowoc Tool and Manufacturing, LLC appreciate the opportunity in working closely with our customers’ engineering team to ensure we fully understand the application of each part we manufacture. Through those conversations drive innovative discussion as to how we can ensure fit form and function – and how from a quality perspective – we achieve parts to print and application every time.

When parts are produced to print – and often times more importantly – to fit form function of the given application, our customers are provided seamless parts which are assembled with ease – thus driving more efficiencies within their walls and driving profitability to another level!
