During welding, the carbon and chromium elements of 300 series stainless steels begin to react with one another, forming chromium carbide. Because the chromium is transformed into chromium carbide, there isn't enough chromium remaining in the steel to form the chromium oxide layer. This results in rust forming in the areas near the weld. By reducing the carbon contents in L-grade steel, the formation of chromium carbide during welding is hindered, and thus, lessens the chance for corrosion along welded joints. Accordingly, it's only necessary to specify L-grade steel for welded components.
