工程常见问题
316L offers better resistance to pitting and crevice corrosion in chlorides and many chemical services. Follow the project material specification.
WP316L is capped at 0.030 % carbon. Standard WP316 may be used where the spec allows higher carbon.
Generally avoid mixing grades in corrosive service without engineering approval. Weld procedures must address dissimilar metals if permitted.
Yes. Other B16.9 fittings in A403 grades can be quoted on the same MTO.
