9HVG
The temperature of critical points of steel 9KHVG: Ac 1 = 750, Ac 3 (Ac m) = 900, Mn = 205. Hardness after annealing (GOST 5950−2000): HB 10 -1 = 241 MPa
thread gauges, patterns of complex shape, the complex is very accurate dies for cold work, which quenching should not be subject to significant volume changes and warpage.
