304 Alloy is developed to work in "as-welded" condition.

Stainless Steel 304 is a variation of the basic 18-8 grade, Type 302, with a higher chromium and lower carbon content. Lower carbon minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In many instances, it can be used in the ”as-welded“ condition, while Type 302 must be annealed in order to retain adequate corrosion resistance. UNS S30400 is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment. SS 304 is also used in the architectural field for exterior accents such as water and fire features.
