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 and external refining.

HEAT TREATTMENT PRACTICE
The preheating of measuring and cutting tool steel is spheroidizing annealing, final heat treatment is quenching + low temperature tempering and hardness after heat treatment can reach 60~65HRC. When heat treat tool steel grades consideration should be given to hardening temperature, including ratio of heating, cooling and soaking times which will differ due to factors such as the shape and size of each chemical component. Other considerations during heat treatment include the type of furnace, quenching medium and work piece transfer facilities.

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.
