Abstract
The effect of low temperature gaseous carburization (LTGC) on pitting corrosion resistance of deformed 304L stainless steel was studied by electrochemical testing. The results show that 62% (volume fraction) α'- martensite (martensite induced by deformation) was found in 304L stainless steel after pre-strain of 45%, and the pitting corrosion resistance in solution containing Br- decreased. After LTGC treatment, the α'-martensite in the surface of 3041. stainless steel disappeared and was transformed into expanded austenite by solid solution of a large number of carbon atoms in it, which improved the pitting corrosion resistance of deformed 304L stainless steel.
