STAINLEESS STEEL FITTINGS GRADES

• 304 – General-purpose grade with good corrosion resistance and formability.
• 304L – Low carbon version of 304 for better weldability.
• 316 – Enhanced corrosion resistance with molybdenum, ideal for marine and chemical use.
• 316L – Low carbon version of 316 for excellent weldability and corrosion resistance.
• 310 – High-temperature resistant; used in heat and oxidation-prone environments.
• 310S – Lower carbon variant of 310 for better weldability in high-temperature applications.
• 321 – Stabilized with titanium; resists intergranular corrosion during welding.
• 347 – Stabilized with niobium; suitable for high-temp, high-stress environments.
• 347H – High carbon version of 347 for better strength at elevated temperatures.
• 904L – Super austenitic steel with excellent resistance to aggressive acids.
• 317 – Higher molybdenum content than 316 for added corrosion protection.
• 317L – Low carbon version of 317 for better weldability.
• Duplex 2205 – High strength and resistance to pitting and stress corrosion.
• Super Duplex 2507 – Superior strength and corrosion resistance for harsh environments.
• 410 – Martensitic steel with good strength and moderate corrosion resistance.
• 430 – Ferritic stainless with good oxidation and corrosion resistance; non-hardenable.
