4Cr9Si2 is a heat-resistant special steel.

4Cr9Si2 Performance:

Martensitic heat-resistant steels, due to their slightly higher chromium content, improve their oxidation resistance and thermal strength, and reduce their sensitivity to tempered brittleness.

It is used in the manufacture of intake valves for internal combustion engines and exhaust valves operating at temperatures below 700, as well as furnace components operating at temperatures below 850.

Heat treatment of materials:

Oil quenching at 1020°C, tempering and air cooling at 760°C, tempering temperature is appropriately adjusted according to hardness.

Heat Treatment Process:

Heat treatment process: 1 phase change point: AC1=900, AC3=970, AR=1810, AR3=870.

2. The initial forging temperature is 1030 1080, the final forging temperature is 850, and the cooling in the pit or sand is cooled after forging.

3 quenching, 1020 1040 oil cooling.

4 tempered, 700 780 oil cooled.
