    Description

    Cast iron CHN19H3SH used: for the manufacture of parts operating under load at elevated temperatures (600 °C); for parts with high corrosion and erosion resistance to alkalis, weak acid solutions, sulfuric acid of any concentration up to 50 °C, in sea water, in the environment of superheated water vapor (exhaust manifolds, valve guides, casings of turbochargers gas turbines, head, pistons, pump bodies, valves and non-magnetic parts).

    Note

    Nickel high-temperature and low alloyed cast iron. Cast iron has a high coefficient of thermal expansion, can be paramagnetic at low chromium content.
