Description
Steel ПКХ25−75 is used: for the manufacture by hot stamping, electrical and electronic structural components (contacts, parts, RF connectors, parts of the waveguide nodes).
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.
