Data presented in this paper will illustrate the problems using ASTM A923 Test Method C for weld procedure qualification for 25% Cr SDSS. While it is an effective test in determining the extent of secondary phase particle precipitation (intermetallics and nitrides) in base metals, it is not appropriate for 25% Cr SDSS weldments, especially the root pass. For 25% Cr SDSS welds, Test Method C is difficult to pass at 40☌, and is essentially non repeatable. This leaves Test Method B (Charpy “V” notch (CVN) testing) and Test Method C (ferric chloride exposure/corrosion rate testing) to qualify the welding procedure for appropriate metallurgical structure.

While Test Method A (electrolytic NaOH) etch can be used as a screening test, it is sometimes not permitted for this purpose by User specifications. While the ASTM standard was initially developed for mill products (base metals), it has become the standard used to qualify Weld Procedure Specifications for DSS and SDSS fabrication.
