Alpha Overseas(AOS) supplies SS 316 / 316L Flanges, which offers rupture and tensile strength at high temperatures. Stainless Steel 316 Flanges is often used for equipment in the chemical, mining, pharmaceutical, petroleum, food, and paper industries. SS 316 Flanges is also used in food preparation equipment, especially in chloride environments. Alloy 316 Slip On Flanges is the preferred steel for use in marine environments because of its greater resistance to pitting corrosion than other grades of steel without molybdenum. Grade 316 Blind Flanges is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. 316 Stainless Steel Flanges also offer higher creep, tensile strength and stress-to-rupture at elevated temperatures. Type 316 Socket Weld Flanges is also common in buildings, site and décor furnishings. These Stainless Steel 316L Flanges are alloys containing chromium and nickel (sometimes nitrogen and manganese), structured around the Type 302 composition of iron, 8% nickel and18% chromium. Compared to chromium-nickel austenitic stainless steels, SS 316L Flanges also offers higher creep, tensile strength and stress to rupture at elevated temperatures.

Stainless Steel 316 Threaded Flanges, SS DIN 1.4404 / 1.4435 RTJ Flanges Suppling at Indonesia, ASTM A182 SS Forged Flanges Manufacturer, Stainless Steel 316L Reducing Flanges, SS 316 / 316L Flanges Manufacturing at Tanzania, Stainless Steel 316 / 316L Flanges Suppling at Belgium, ASME 16.47 Series B Steel Flanges Manufacturer & Stockist in Mumbai, India.

Alloy 316L Weld Neck Flanges is excellent in a range of atmospheric environments and many corrosive media - generally more resistant than 304. Grade 316L Orifice Flanges are also both non-hardenable by heat treatment and can be readily formed and drawn. 316L Stainless Steel Flanges can be formed from the annealed temper by stamping and deep drawing.

The low carbon in Type 316L Ring Type Joint Flanges provides resistance to sensitization during welding and other thermal processes.
