Stainless steel 304L buttweld fittings contain a special set of chemical, mechanical, and physical properties to suit applications in a broad variety of industrial processes. SS 304L is chemically constituted of iron, 18–20% chromium, 8–12% nickel, and up to 0.03% carbon, which improves its corrosion resistance as well as weldability by reducing carbide precipitation during welding. Mechanically, the fittings provide good tensile strength, superior toughness, and high stress corrosion cracking resistance. Physically, 304L fittings possess a density of approximately 8.0 g/cm³, a melting point of around 1400–1450°C, and retain structural integrity in high-temperature and low-temperature conditions.
