Cast iron CHH22S
Designation
Description
Cast iron CHH22S used: for the manufacture of parts with high corrosion resistance in hot gas environments at temperatures up to 1000 °C (part, not exposed to permanent and variable loads; details of the equipment for nitric and phosphoric acids, chimney fittings).
Note
Chromium corrosion and heat-resistant high-alloy cast iron. Cast iron acid-resistant and resistant to intergranular corrosion.
Standards
Chemical composition
Fe is the basis.
According to GOST 7769-82, nickel content is allowed up to 1.0% or copper up to 1.50%, introduced by natural alloyed iron, alloyed with steel scrap or magnesium-containing ligature.
