Ittemprar artab:

Saħħan għal 710-850 ° C, kessaħ bil-mod fil-forn. Dan se jipproduċi ebusija Brinell massima ta '223.

It-Taffija tal-istress:

Stress relieving to remove machining stresses should be carried out by heating to approx. 650C, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Ebusija:

Harden from a temperature of 780-820°C, 800-840°C followed by water or oil quenching. Hardness after quenching is 64-66, 64-66 HRC.

Ittemprar:

Tempering temperature: 100-400°C.
