Fitwel Industries LLP, an ISO 9001:2015 certified company, a top leading manufacturer, suppliers, and exporters of ASME SA403 Stainless Steel 321 / 321H Buttweld Fittings, SS 321 Pipe Fittings, that are produced with the finest raw materials. Columbian stabilized Alloy 347/347h is an Austenitic Steel-type that bears good resistance to general corrosion. It offers somewhat better resistance in strong oxidizing conditions than that of 347. It allows for the elimination of carbide precipitation and resists intergranular corrosion. It bears higher creep and stress rupture properties than Alloy 304 and 304L. Hence, it can be exposed to conditions where sensitization and intergranular corrosion are a concern.
Our SS UNS S34700 / S34709 Butt Weld Pipe Elbow finds application high-temperature chemical processing, high-pressure steam pipes, radiant superheaters, etc. We offer SS DIN 1.4550, 1.4961 Butt Weld Bends in a variety of types such as Tees, Reducers, Cross, Elbow, Stub Bends, and End Caps. All our products undergo strict quality checks to ensure their durability and reliability. We use state-of-the-art machinery and equipment to manufacture all our products. Our products are available in complete customization options to ensure all the customer requirements are met.
