Ni-Resist Type 2, Austenitic Cast Iron
Ni-Resist irons contain an austenitic matrix with about 5-10% alloy carbides. The austenitic structure is suitable for corrosive environments in sour well oils, salts, salt water acids and alkalies. The iron is relatively soft and chrome is added to produce carbides that help improve wear resistance. Ni-Resist is more dense than gray or ductile irons and will have a higher coefficient of thermal expansion. Ni-Resist is manufactured to produce a material conforming to ASTM A436, Type 2.
