For large steel assemblies in particular, PWHT can be an expensive operation, and there is thus an economic incentive to avoid PWHT, wherever possible.

Unlisted materials can still follow all the requirements of D1.1, so as you said the reduced section tension test is necessary as well as the macros to ensure fusion to the root.

But, I do not recall any specific requirement that SA515 was singled out for PWHT as a Code rule.

Aug 22, 2017Sometimes post-weld heat treatment (PWHT) is required for stress relieving both the weld metal and heat-affected zone in A517 Quenched and Tempered (QT) steels. This process unavoidably results in further tempering which adversely affects the mechanical properties of the welded joints.
