- Aug 24, 2018 -

H13 die steel is used to produce forging dies with large impact load, hot extrusion dies and fine forging dies. Aluminum, copper and its alloy die casting mold. H13 can also be used for wood chipper knives.

Electroslag remelting steel, the steel has high hardenability and thermal crack resistance, the contain higher content of carbon steel and vanadium, good wear resistance, toughness is relatively less, has good heat resistance, high temperature has good strength and hardness, high wear resistance and toughness, excellent comprehensive mechanical properties and high resistance to tempering stability.But even so, the A8 is still the best choice for wood chipper knife.
