Material Name: Alloy tool steel
Grade: 5CrW2Si
Standard: GB / T 1299-1985
characteristics and the scope of application of:
Shock-resistant tool steel, composition, performance and similar
4CrW2Si. As the cold steel, the wind can be used to manually move
chisel, air hammer tool, rivet tool, and cutting-edge of cold
blanking die, as well as long-term work of carpentry tools. For
thermal processing of steel, the tool can be used as a punching or
piercing shear modulus, hot forging dies, die-casting alloy easy
mode, as well as hot and cold shear cutting blades and other
metals?,
