Page 1: Ni Alloy Steels

Alloy SteelsNickel is an important alloying addition to low-alloy steels (apart from stainless steels discussed above) where itimproves strength and toughness whilst retaining good ductility in engineering components such as gears andtransmission shafts. Nickel improves the low temperature toughness of ferritic steels, enabling them to be used forcryogenic applications. For example, 9% nickel steel is used for LNG handling and storage. It also contributes to highstrength steels and the “maraging” steels can be produced with particularly high tensile strengths. Nickel is alsoimportant in some carburising, nitriding and tools steels.
