304L Stainless Steel Plate contains at least 18% chromium and 8% nickel. Chromium can react with oxygen to form a dense oxide film, which protects the SUS 304L surface from corrosion. Nickel can improve the oxidation resistance and corrosion resistance of stainless steel. The "L" in the name of 304L stands for the low carbon content, which can resist intergranular corrosion. ASTM A240 SS 304L plate can be cut, drilled, punched and bent at will with high precision and good surface quality.
