This investigation examines the intergranular corrosion resistance of both welded and unwelded type 304, 304L, 321,321L, and 347 alloys after various sensitizing and or stabilizing heat treatments. The intergranular corrosion resistance was charactorized using ASTM A262 test methods and the double loop electrochemical potantiodyrmmic reactivation testing (EPR). The results show that stabilization by itself is not sufficient to render austentic stainless steel immune to sensitization.
The EPR testing demonstrates that the double loop...
