Overview

Grades

Dual phase grades

Cold-rolled dual phase steels allow you to increase the strength of the finished component or reduce the thickness of the steel - or both. By increasing product performance and helping reduce weight, these steels support you to achieve your optimum performance parameters. The use of dual phase grades increases the output from each tonne of steel and produces products that are strong, light and safe under load. High strain-hardening capacity ensures our dual phase steels have good formability.

Hot forming steel - HQ1500 CR

Our HQ1500 CR product is an uncoated, ultra high-strength hot forming steel. It combines a strength level of 1500 N/mm2 with excellent shape accuracy. Compared with conventional high-strength, low-alloy grades, HQ1500 CR offers real opportunities for weight reduction through down-gauging. It also ensures good repeatability in long production runs when compared with cold press forming.

 

Applications

  • Automotive body-in-white
