Alloy 304L

Alloy 304L - Austenitic Stainless Steel

Alloy 304L is a low-carbon version of 304 stainless steel, offering excellent corrosion resistance, high strength, and good weldability. It is widely used in industries where resistance to corrosion is required, particularly in environments that involve acidic or chloride-rich conditions. The lower carbon content helps to reduce the risk of carbide precipitation during welding, making it ideal for welded applications.
