BBN ultra-high strength steel is favored by high-end customers

Since the beginning of this year, the sales volume of BBN 780MPa and above high-strength steel has continued to break through.

As a pillar industry that penetrates into daily life and has a wide range of influence, the automobile industry naturally has a great responsibility for energy conservation and emission reduction. Especially in the research and development process of a new generation of automotive products, starting from materials and reducing the body weight as much as possible on the premise of ensuring quality is the core path for automakers to reduce carbon emissions.

For example, the ultra-high-strength steel with a tensile strength of not less than 1000MPa, as the representative product of the third-generation super-automotive high-strength steel, can reduce the body weight and reduce energy consumption while ensuring the strength.

The production of such ultra-high strength steel requires processes from steelmaking, hot rolling to cold rolling, etc., to achieve long-term high-level connection pipes and precise control, in terms of reducing body weight, improving automobile safety performance, realizing energy saving and emission reduction, and application transformation of steel products. There are many technical bottlenecks, it is the technical commanding height of the steel industry, and it is also a high-tech product to test the comprehensive strength of steel enterprises.
