Description

Cast iron S-Ni22 is used: for the manufacture of casting parts for pumps, valves, compressors, bushings, housings turbochargers, parts of the exhaust piping.

Note

Nickel cast iron. Cast iron S-Ni22 has a high coefficient of thermal expansion; a lower corrosion resistance and lower heat resistance than cast iron brand L-NiCr20−2. Cast iron S-Ni22 has good features dynamic influence down to minus 100 °C. the Magnetic properties has not.
