Good news came from Hebei Iron and Steel Group, Handan Iron and Steel Company's western plant successfully trial produced automotive phase transformation induced plasticity steel TRIP380/590. After testing, its chemical composition met the standard and the quality of the cast slab was completely qualified. The successful smelting of this product will further enrich and optimize the product structure of Handan Iron and Steel automobile steel, opening the curtain on advancing to 780 megapascals and above high-strength steel levels.
It is reported that the car plates rolled from this product, compared with other same-level high-strength steels, have higher strength, higher elongation performance, higher collision absorption performance, and can significantly reduce the body thickness and lower fuel consumption. They are commonly used in car bumpers, car chassis and other anti-collision parts. This steel also has excellent high-speed mechanical properties and fatigue properties, which are highly favored by automakers and have good market prospects.
This grade belongs to Handan Iron and Steel's key developed series of automotive steel products. Due to its special components, it requires a high level of control in various processes such as converter, refining, and continuous casting. For this reason, the western plant formulated a detailed process plan, overcame difficulties such as continuous pulling of different grades of steel, ensuring the success of the first smelting of this grade.
