MELTING PROCESS
This steel 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
1.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.
2.Cutlery for medical equipments
3.Cutting tools
4.Mechanical parts
5.Air hammer tools
6.Piercing tools
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.
