Abstract
A chrome-nickel steel consists, by weight, of from 0.03% to 0.10% carbon, up to 1.0% silicon, up to 1.0% manganese, from 14.50% to 16.50% chromium, from 5.0% to 6.50% nickel, from 2.1% to 3.0% molybdenum and from 0.03% to 0.10% nitrogen the remainder except for impurities, iron. The composition of the steel satisfies the following conditions:- CrA/NiA = 1.8 to 2.6 (%Cr) + 3.3 (%Mo)>/=22 where CrA = (%Cr) + (%Mo) + 1.5 (%Si> and NiA = (%Ni) + 0.5 (%Mn) + 30 [(%C) + (%N)]. The steel has high strength and corrosion resistance combined with higher ductility and better weldability than conventional 18/8 austenitic steels.
