Description
Cast iron CHN11G7SH used: for the manufacture of 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 (600 °C) and low high alloy cast iron. Cast iron has a high coefficient of thermal expansion, can be paramagnetic at low chromium content.
