Welding 304 stainless, yield strength in heat affected zone

Welding 304 stainless, yield strength in heat affected zone

Welding 304 stainless, yield strength in heat affected zone

(OP)
Hi, I have not dealt much with stainless weldments. What yield strength can be expected to be left in the heat affected zone of my welded joints? I need these numbers for calcs on a stainless frame I am designing that will have a small picker crane on top. Thx!

RE: Welding 304 stainless, yield strength in heat affected zone

The good news is that for austenitic stainless steels, like 304, these are non-hardenable grades by heat treatment. Assuming the stainless steel is in a solution treated condition, the HAZ would exhibit nearly the same YS values as solution treated base material.

RE: Welding 304 stainless, yield strength in heat affected zone

The bad news is that the YP is pretty low, like 25 ksi, relative to CS, usually 36 ksi or more.

But at least it is the same yield that was used in the design.
Many grades have a 30ksi min yield, and they typically come in 35-45ksi for actual properties.

Did anyone use a WPS - qualified Weld Procedure Specification?? The PQR - procedure qual coupon will have given that datum.

RE: Welding 304 stainless, yield strength in heat affected zone

The UTS is all that is required to be recorded on the PQR. The YS may be eroneous due to the influence of deposited weld metal.

If you design to 'typical' or 'measured' YP, expect to get an angry phone call not long after a lot with 'minimum' YP arrives.
