A 1.5-gigapascals Martensite Steel Plate Was Developed
Hyundai Steel has developed a 1.5-gigapascals martensite steel plate for automobiles.
Recently, Hyundai Steel announced that it has developed a 1.5-gigapascals martensitic steel plate for automobiles, which is significantly improved in flatness and crack resistance compared to similar products. For effective differentiation, the product is designated as a high-grade 1.5 Gigapasic martensitic plate.
It is reported that a 1.5-gigapascals martensitic steel plate needs rapid cooling to ensure high strength in the manufacturing process and the flatness of the steel plate will be reduced. In the process of using, due to hydrogen penetration which produces the crack, quality is difficult to guarantee and in the field of the automotive plate, the manufacturing application is also very limited. To solve these problems, Hyundai Steel optimized the combination of the alloying element from the raw material production stage, and developed heat treatment techniques that replace rapid cooling and minimize hydrogen permeability, thereby reducing the probability of crack generation.
