| Nickel
(plus carbon, manganese, and nitrogen) promotes the
formation of austenite, and chromium (plus silicon,
molybdenum, and niobium) encourages the formation of
ferrite so the structure of weld in stainless steels
can be largely predicted on the basis of their chemical
composition. Because of their different microstructures,
the alloy groups have both different welding characteristics
and susceptibility to defects. |
