    Description

    12KHM steel is used: for the manufacture of hot rolled plates; pipes of superheaters and pipelines and collector installations high pressure; and parts parts of boilers and vessels working under pressure at ambient, elevated and sub-zero temperatures; as the base layer in the manufacture of hot-rolled dual-layer corrosion-resistant sheets.

    Fe is the basis.
    According to GOST 5520-79 in the manufacture of steel scrap-process, the mass fraction of copper should not be more than 0.30%.
    According to TU 108.1263-84, steel should be smelted in an open-hearth furnace or an electric arc furnace. It is permitted to process steel at the OSRP.
