Description

Cast iron CHNHMDSH used: for the manufacture of parts with high mechanical properties, wear resistance and corrosion in slightly alkaline, gaseous media and aqueous solutions (blocks and cylinder heads, exhaust pipes of internal combustion engines, steam engines and turbines; pistons and cylinder liners, steam engines, diesel and marine diesel engines; detail the oxygen and gas motorcompressors, parts of paper machines).

Note

Nickel is corrosion resistant in gaseous environments of low alloy cast iron high tensile strength.
