Description
Cast iron CHN15D3SH 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 (pumps, valves and other fittings of oil, chemical, petroleum and valve manufacturing; non-magnetic castings electrical industry; insertion of cylinder liners, heads, pistons, valve seats and valve guides and exhaust manifolds of internal combustion engines).
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.
