Abstract

An austenitic nickel-chromium-iron alloy consists of .C.traces-0.15% .Mn.traces-1.0% .Si.traces-1.0% .Cr.10.0-22.0% .Ni.25.0-60.0% .Mo.traces-6.0% .Nb.0.5-7.5% .Ti.1.5-5.0% .Al.traces-2.0% .B.0.001-0.02% the balance, apart from incidental impurities, being iron. The niobium may contain normal amounts of accompanying Ta. The alloys may be heated at 1900-2100 DEG F. and hot or cold worked. They are then solution-treated at 1800-2100 DEG F., quenched (e.g. in water), aged at 1150-1450 DEG F. and then air cooled. A secondary ageing step at 1150-1300 DEG F. followed by air cooling may also be applied.
