Heat treatment

Annealing

Annealing of this material can be performed by heating uniformly to 840-900°C (1544-1652°F) and

held until the temperature is uniform throughout the section.

Soaking and cooling is required.

Hardening

Stainless steel grade 3Cr13 can be hardened by heating 950- 1020°C (1742-1868°F) and

held until temperature is uniform throughout the section.

This should be followed by quenching in oil or air cooling.
