Dear All,We have to weld an Ø1½" SS 304 guide pin pipe to Ø4" 5Cr furnace tube. I was unable to find any WPS in our records. Some research I did revealed that I should be using SS 309 for the welding. What I am concerned is whether Stress relieving is necessary? I learned from somewhere that it will lead to sigma phase creation and carbide percipatation in austenitic stainless steel.Your comments / help is much appreciated.Regards,Muhammad Ali--
