    Description

    Cast iron CHNHMD used: for the manufacture of parts with high mechanical properties, wear resistance and corrosion in slightly alkaline, gaseous media (internal combustion engines and technical oxygen) and water solution (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, parts and oxygen gas motorcompressors, parts of paper machines).

    Note

    Corrosion resistant Nickel alloyed cast iron.
