    Description

    Cast iron L-NiCr20−3 is used: for the manufacture of working in high temperatures: casting pump parts, pump lye; for vessels, which contain caustic alkali; parts soap and food industries, industries for the production of artificial silk and plastics; suitable in cases where the required materials not containing copper.

    Note

    Nickel cast iron. Has properties similar to Marche L-NiCuCr15−6-2 and L-NiCr20−2, but with a higher resistance to erosion, high heat resistance and a high degree of expansion.
