Overview

CJM is a trusted supplier of carbon and alloy steel in China, with over 1 million tons of inventory. We offer high-strength hot formed and hot stamping steel plates widely used in automotive crash-resistant structures. With global delivery to Southeast Asia, the Middle East, Africa, Europe, and the Americas, we support custom sizes, fast delivery.

What is Hot Stamping Steel?

Hot stamping steels are ultra-high strength steels formed at high temperatures, allowing complex shapes while maintaining superior crash performance. They are commonly used in automotive safety components such as A/B pillars, bumpers, and door beams.

Available Steel Grades

We supply the following common hot stamping / hot forming grades:

• 22MnB5 (EN 10083-3 / DIN 17222 standard)
• 20MnB5
• BTR165, BTR150, BTR240 (press hardening steels)
• CR950Y1470T-MS (Martensitic steel)
• PHS1500 (Press-Hardened Steel)
