.... There was no evidence of crevice corrosion or any localized penetration of tubes that had sound welds. The leaking type 309S (Nb) welded tubes should be replaced with seamless tubes of type 304L stainless steel to minimize the areas requiring welding and to provide maximum weldability for the tube-sheet...

... testing can also create problems. In one instance, welds were being made successfully on a steel containing more than 0.35% C, but because the normal borderline weldability of this material made it susceptible to cracking, a magnetic-particle test was done to check for cracks. No cracks were found, but a...

... microstructure typical of a medium-carbon steel (carbon approximately 0.4%) in the normalized condition, a material not weldable by ordinary methods. It was concluded that the post-welding crack arose primarily from the thermal contraction which developed in the weld metal on cooling. It is probable that if the...

... cooled through this range—a condition which could arise in a casting. An analogous effect also occurs during welding, hence the use of the term weld decay to describe corrosion of this form in fabricated articles. It is usual, in steels of weldable quality, to add titanium or niobium, the so-called...
