PRODUCT DETAILS
Product Description
Docol 420HE:Docol HR420Y480T HE is the next generation of hot-rolled high-strength low-alloy steels with better local formability, resulting in higher edge ductility and better trim quality. Docol HR420Y480T HE uses a new and closely controlled method of production, fine metallographic structure, is a pure steel, greatly improved local formability, while still maintaining good overall formability, suitable for stamping most geometric shapes, and in cutting edge quality affects the feasibility of forming applications. Compared with the traditional SLA grade, this new method of production DocoHIR420Y480T HE has improved the quality of cutting edges, and the steel can well adapt to the requirements of mold adjustment and wear resistance, so it is especially suitable for precision blanking.
