Zusammenfassung:The alloy of the parent Specification is modified in that it contains: ..Cr.16 - 17% ..C.0.04- 0.08% ..Mo.3 - 3.5% .and.Ni.37 - 50% The titanium content is preferably 1-25% and the maximum nickel content is preferably 45%. The heat treatment disclosed comprises solution heating at 1080 DEG C. for 8 hours, air cooling, ageing at 700 DEG C. for 16 hours and again air cooling.
