The optimal heat treatment for 13Kh steel blades consists of quenching from 820±10°C (holding 6–8 sec) and tempering at 200–220°C.
This heat treatment produces a fine-grained structure with evenly distributed fine carbides, a hardness of HRC 62-64, reduces distortion and rejects, and substantially increases the durability of the blades.
