Description
Steel ПК20Х13М2−74 is used: for the manufacture by cold deformation sredneshirotnykh structural components used in mechanical engineering and instrument making; tool holders of the tool; after heat treatment for parts operating under alternating loads and subject to wear.
Note
Powder steel is corrosion resistant.
The material should be applied after the impregnation with compounds that protect against internal corrosion. Compositions for the impregnation in accordance with OST 4G 0.054.213.
