Delta ferrite-containing austenitic stainless steel resistant to the formation of undesirable phases upon aging

Patent ·

OSTI ID:5419075

Leitnaker, J M

Austenitic stainless steel alloys containing delta ferrite, such as are used as weld deposits, are protected against the transformation of delta ferrite to sigma phase during aging by the presence of carbon plus nitrogen in a weight percent 0.015 to 0.030 times the volume percent ferrite present in the alloy. The formation of chi phase upon aging is controlled by controlling the Mo content.
