Material Name: Alloy tool steel
Grade: 6CrW2Si
Standard: GB / T 1299-1985
● Features and application:
Impact-resistant tool steel, composition, performance and 5CrW2Si similar single higher quenching hardness and high temperature strength. Often used as wear resistance to withstand high impact loads but requires tools such as pneumatic tools, chisels and heavy-duty work performance molds, cold shear blades, pneumatic hammers and other tools.
