Effect of initial state on the aging behavior of austenitic stainless steel filler metal

Conference ·
OSTI ID:7142037
;
Type 308 stainless steel is commonly used as a filler metal for austenitic stainless steel weldments. Welds produced by conventional processes contain a duplex austenite plus ferrite microstructure. However, after a solution anneal, the welds may contain a fully austenitic microstructure without ferrite. The elevated temperature stability of this steel was investigated after aging between 550 and 850/sup 0/C for up to 10,000 h. Three different initial conditions were examined: solution annealed and quenched; solution annealed, quenched, and cold worked; and as-welded.
