Sulphur Content in Laser Welding
Sulphur Content in Laser Welding
(OP)
I've been told the sulphur content must be very low to weld 303 stainless steel (maybe .2 max). Getting 303 with this low of a sulphur content is very difficult. Does anybody know how low you have to go to weld with 303? Could a process parameter compensate for higher sulphur?
Thanks
Thanks

No 304 with 0.2% S, since 304 has the limit of 0.030% S, maximum.
303 contains 0.15% S, minimum, usually ~0.3%.
Carpenter Technology has improved machining versions of 304 & other SS, within the standard composition limits so no welding problems. Register at their website (free) & download info:
