Labdhi Metals is a reputed manufacturer, stockist, and exporter of high-quality Stainless Steel 321 Fittings, catering to a wide range of industries that demand superior resistance to high temperatures and corrosive environments. SS 321 is a titanium-stabilized austenitic stainless steel designed to resist intergranular corrosion, especially after welding or prolonged exposure to elevated temperatures. Labdhi Metals provides a comprehensive range of SS 321 pipe fittings, including elbows, tees, reducers, caps, and customized configurations for various industrial piping systems.
Stainless Steel 321 fittings are highly suitable for use in high-temperature applications such as exhaust manifolds, heat exchangers, furnaces, jet engine parts, and chemical processing equipment. The addition of titanium in SS 321 helps prevent chromium carbide precipitation during welding, which makes it particularly effective in welded structures exposed to temperatures between 430°C and 870°C. Labdhi Metals manufactures these fittings with precision and strict quality controls to ensure durability, dimensional accuracy, and long service life.
The fittings are available in various types such as buttweld, socket weld, and threaded, and come in a wide range of sizes and pressure classes. These fittings are manufactured as per international standards such as ASME B16.9, B16.11, MSS-SP-43, and are offered in seamless and welded forms. Labdhi Metals also provides custom fabrication services to meet unique project specifications and client requirements.
As a prominent stockist and exporter, Labdhi Metals maintains a large inventory of SS 321 fittings for immediate delivery across domestic and international markets. The company exports to countries such as the USA, Germany, UAE, Saudi Arabia, South Africa, and more. All products are supported by material test certificates (MTC), third-party inspection reports, and documentation that complies with ASTM A403 / ASME SA403 and other relevant standards.
