SS 321/321H Fittings & Flanges – Buttweld, Forged & Outlet Types – Engineered for Thermal Processing, Petrochemical & Refinery Use – NACE, PED, IBR Approved. We are a recognized ISO-certified manufacturer and exporter of premium stainless steel products, offering a comprehensive range in Stainless Steel 321 – a titanium-stabilized austenitic stainless steel ideal for high-temperature service. Our product line includes SS 321H Buttweld Fittings, Flanges, Forged Fittings, and Olets, engineered for long-term durability in applications involving elevated temperatures and intergranular corrosion risks. With modern manufacturing capabilities and a strong global supply chain, we serve industries such as heat exchangers, refineries, power generation, and chemical processing. Stainless Steel 321H provides excellent resistance to oxidation and scaling at high temperatures, and superior weldability due to its titanium stabilization which prevents carbide precipitation. Our fittings and flanges are manufactured as per global norms: ASTM A403 / ASME B16.9 for Buttweld Fittings, ASTM A182 / ASME B16.5 & B16.47 for Flanges, ASTM A182 / ASME B16.11 for Forged Fittings, and ASTM A182 / MSS SP-97 for Branch Outlet Fittings. We offer buttweld fittings from 1/2” to 48”, forged fittings from 1/8” to 4”, and flanges from 1/2” NB to 24” NB in pressure ratings from 150# to 2500#. All materials come with full traceability and certification as per EN 10204 3.1 or 3.2. We manufacture a complete range of SS 321 Buttweld Fittings, including elbows (90°/45°), concentric and eccentric reducers, equal/reducing tees, caps, and stub ends. Our forged fittings are available in Socket Weld and Threaded ends, including elbows, tees, couplings, unions, caps, plugs, bushings, and swage nipples in accordance with ASME B16.11. Our flanges are produced in multiple types like Weld Neck, Slip-On, Blind, Socket Weld, Lap Joint, Threaded, and Orifice designs. We also supply branch connection fittings such as Weldolets, Threadolets, Sockolets,…
