Stainless Steel 321 Flanges Manufacturer, Suppliers, Exporters – SS 321H Slip On Flanges, S32100 Flanges, S32109 Flanges, 1.4541 Flanges, 1.4878 Flanges
- We are manufacturing Stainless Steel 321/321H flanges in various sizes and material standards. We can also manufacture your specific flange requirements in short delivery time. Metallica is India’s leading exporter and manufacturer of Stainless Steel 321/321H flanges, with monthly production and sales of over 2000 tons. Most of our production of carbon steel flange and stainless steel flange exported out of India to over 45 countries.
- Standard specification of Stainless Steel 321/321H Flanges is ASTM A182 / ASME SA182.
- A steel flange (forged, cut from plate, or rolled) comes in a variety of shapes and sizes to suit different applications. A flange is usually in the shape of a round disc and is used to connect two pipes together or to connect a pipe to a pressure vessel, valve, pump, integral flanged assembly or other component. A flange comes with holes for bolts around the rim. Bolts are used to connect two flanges which are typically attached to pipe ends with a gasket in between.
- Stainless Steel 321/321H Flange temperature and pressure tolerances are dependent on the rating. We specialize in producing high purity uniform shaped Stainless Steel 321/321H Flanges. We also offer custom flanges with annealed or hard tempers and will meet most of the common Milspec or ASTM standards.
- Stainless Steel 321/321H Flanges are available in multiple shapes, as welding neck (the pipe is welded to the collar of the flange), threaded (the pipe is screwed on the flange), socket weld (fillet welds connections), lap joint (for connections using stub ends), slip on, etc. A Stainless Steel 321/321H flange can also be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.
- The ASME B16.5 and ASME B16.47 specifications cover US standard pipe flanges, the EN 1092-1 specification covers European steel flanges.
- A Stainless Steel 321/321H flange can be produced and designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

Prices for Stainless Steel 321/321H Flanges
Prices for stainless steel 321/321H Flanges are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy plates is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
