Weld joint strength reduction factor for 16-8-2 weld metal
Weld joint strength reduction factor for 16-8-2 weld metal
(OP)
Hello all,
B31.3 sec. 302.3.5 and 304.1.2 have weld joint strength reduction facotr W to reduce the allowable stress for high temperature service. I have a 48" stainless steel 304H welded duct at design temperature 1450 degF. If I use 16-8-2 weld metal instead of 308H weld metal, can I take W=1 for thickness and pipe stress analysis ?

You may be able to claim "W = 1", but you have to do your homework.
