Abstract

The effect of post weld heat treatment (P.W.H.T) on the propagation rate of stress corrosion cracking(S.C.C) and threshold stress intensity factor ($K_{IC}.c.c$) for stress corrosion cracking of 304 stainless steel has been investigated in boiling 45% $MgCl_2$ solutions with W.O.L specimens. Specimens were precracked by turning a pair of Cr-Mo steel bolts into a machined slot at the end of the specimen. The fracture surface was examined fractographically by Scanning Electron Microscope(S.E.M.)
