Annealing Quenching Tempering Aisi M4 Steel Production Specifications - China

M4 High Speed Steel Heat Treatment

(1) Thermal processing specifications

The starting temperature is 1040~1150℃ and the ending temperature is 930℃.

(2) Annealing specifications

Usually, the annealing temperature of M4 high-speed steel is controlled at 870~900℃, kept warm for 4~6 hours, and then cooled in the furnace.

After cooling to a certain temperature, the heat preservation continues, and finally it is air-cooled out of the furnace.

(3) Quenching specifications

First, preheat M4 steel to 730~850℃, control the quenching temperature at 1024℃ (salt bath furnace), box furnace 1210~1230℃, and the quenching medium is oil, air cooling or salt bath.

(4) Tempering specifications

The tempering temperature is generally controlled between 540 and 560°C.

It requires multiple temperings, one hour each time, and air cooling to room temperature.
