Description
Cast iron CHN3HMDSH used: for the manufacture of parts with high mechanical properties, wear resistance and corrosion in slightly alkaline, gaseous media (products of fuel combustion, technical oxygen), aqueous solutions and melts of caustic soda (different types of gears, cylinders, engines, grinding wheels, throttles, cooling cylinders and shafts paper, Board and drying machines, matrix, punch presses).
Note
Nickel low-alloy wear-resistant cast iron of increased strength.
