Weldability of 904L CRES
Weldability of 904L CRES
(OP)
I have been tasked to write a welding procedure for 904L CRES. I have no experience with this grade. Does anyone know a Milspec or ASTM that this grade is manufactured to? My particular questions are welding parameters such as, preheat, filler, PWHT requirements.





RE: Weldability of 904L CRES
904L welds like any high alloy stainless.
Filler, I think that NiCrMo3 (385?) is a slightly over alloyed filler for this.
There are ASTM specs, B674 is a tubing spec. I don't recal the sheet/plate specs.

Manage it or it will manage you.

The paper above provides an excellent guidelines for welding of stainless steels including background information, welding processes, cleaning, weld joint design, suggested filler metal, etc.
