All stainless steel fabrication can only be done using tools designed for stainless steel materials. Tools and work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross-contamination of stainless steel with easily corroded metals that may discolor the surface of processed products.
The lower carbon content of 304L alloy helps to minimize/eliminate carbide precipitation during welding. This allows 304L stainless steel to be used “as welded”, even in severely corrosive environments. Basically, using 304L eliminates the need to anneal welded joints before using the full metal form, saving time and effort.
