Stainless Steel 317 Fittings Manufacturer and Exporter
The Stainless Steel 317 Fittings are mainly manufactured from high-strength, high-resistance, excellent corrosion-resistant materials, as they are used in the harsh environment of industry. Stainless steel 317 Fittings are a type of austenitic stainless steel fittings. Chromium, nickel and molybdenum contents are higher in these fittings than other stainless steels. The SS 317 fittings are easily welded, formed and do not sensitize during welding and thermal treatment. They have high tensile strength and stable performance at high temperatures as well. These fittings are manufactured to ASTM A403 / ASME SA403 and ASME B16.9 specifications and come in elbows, tees, reducers, bends, stub ends, etc. Solitaire Overseas is a well-known manufacturer and supplier of high-quality Stainless Steel 317 Fittings, precision-engineered for the chemical processing, petrochemical, marine, power generation and oil and gas industries around the world.
