The chemical composition of SS 304/304L is designed to offer strong resistance against oxidation, chemicals, acidic environments and chloride-bearing waters. Containing 18–20% chromium and 8–12% nickel, the alloy provides an excellent balance of corrosion resistance and ease of fabrication. The reduced carbon level in 304L makes it more weld-friendly, especially for high-temperature and pressure-rated applications..
