FIELD: process engineering.
SUBSTANCE: invention relates to machine building. Method of production comprises preparing the melt, filling the melt into mould, producing casts, annealing, machining surface hardening and polishing. Surface hardening is performed by tempering at the temperature of 50…40°C lower than preset one, while one-time tempering is performed at the temperature 20…60°C lower than preset one.
EFFECT: higher efficiency of casting.
