304L stainless steel bar is one of the most versatile stainless steel products. This grade is calcium-treated stainless steel obtained through special steelmaking practices designed for calculated and precise control of non-metallic inclusions. These inclusions have specific morphology and lubricating properties, which can improve machinability. Tool wear is reduced and chip breaking is increased due to the formation of a layer between the tool and the chip. 304L stainless steel rod has a low carbon content and a high chromium content. It has good strength, easy formability, and excellent corrosion resistance, including corrosion protection when welding. While 304 stainless steel rods can sometimes be used in the “welded condition”, 304L is more commonly used in the “welded condition” due to its additional protection against corrosion.
