1.2347 Die Steel
Equivalent grades: FDAC/DH2F
1.2347 die steel has excellent mechanical processing performance and polishing performance. It owns extremely high toughness and ductility in every aspect; it has high thermal cracking resistance.
It has excellent wear resistance in both high and low temperature, excellent quenching Permeability, good resistance to high temperature and thermal fatigue resistance; quenching deformation is small. It have a better isotropic (isotropic) than conventional smelting steel. It can be nitriding and has other advantages. The indicators no matter before and after the heat treatment , are better than 1.2344 hot work die steel.
1.2347 die steel is mainly used in the production of light alloy die-casting mold; steel forging forming mold and mold insert; extrusion die; heavy alloy mold bearing and guide sleeve; the formation of heavy and medium alloy pressure mold; plastic mold (Injection mold) and so on.
