HC260Y Cold Rolled Steel Plate
HC260Y is a low alloy, low alloy medium carbon martensite strengthened ultra high strength steel (MART) is developed on the basis of low alloy quenched and tempered steel, and the total amount of alloy elements is generally no more than 6%.
HC260Y is a high strength steel without interstitial atoms. The chemical composition of the steel is controlled to improve the plastic strain ratio (r value) and strain hardening index (n value). Due to the solid solution strengthening of elements in steel and the microstructure without interstitial atoms, this kind of steel not only has high strength, but also has very good cold forming properties. It is usually used to make complex parts that need deep stamping, which are widely used in ships, vehicles, aircraft, railways, bridges, pressure vessels, machine tools and other structures.
