MELTING PROCESS 
This alloy is generally smelt in electric arc furnace  (EAF ) or IFF + VD, LF + Electroslag remelting (ESR).
For a purpose of higher quality, it should be smelt via technology of vacuum refining.
TYPICAL APPLICATIONS
Alloy tool
steel is widely used to produce the cutting tool, cold/heat distortion mould and measuring implements,
and further to manufacture the piston, valve, valve seat of fuel pump of diesel engine.
Cutting tools
Mechanical parts 
Air hammer tools
Piercing tools
FEATURES AND CLASSIFICATIONS
Hot-work die divides into several main types, such as hammer forging, die forging, extrusion and die casting, including hot forging die, press machine forging die, stamping die, hot-extrusion die, metal die-casting mould. Heat distortion mould not only supports huge mechanical stress, but also thermal stress during working repeatedly. Hot-work die steel should have not only high hardness, red hardness, abrasion resistance, toughness, but also have excellent high temperature strength, thermal fatigue stability, thermal conductivity, upper hardenability for guaranteeing the whole cross section with consistent mechanical property.
