Detailed Information

Prashaant Steel & Alloys is a well-known maker and retailer of Flanges for Stainless Steel 321 in the market. We produce ASME SA182 SS 321H Flanges that follow global and national quality requirements by using the best quality raw materials. The ASTM A182 SS 321 Flanges have a high corrosion and oxidation resistance thanks to the right mix of nickel, chromium, and titanium. Except at high temperatures, the ASME SA182 SS 321H Flanges are produced to have improved performance at low temperatures. Flanges of this kind can tolerate temperatures of up to 870 degrees Celsius. The ASTM A182 SS 321 Flanges have excellent machinability and production characteristics. Prashaant Steel & Alloys is known for manufacturing high-quality goods that match or exceed our customers’ needs. Prashaant Steel & Alloys is known for its stainless steel 321 Flanges. We manufacture and sell a wide range of ASTM A182 SS 321 Flanges. ASME SA182 SS 321H Flanges preserve strength and corrosion resistance even when exposed to high temperatures. Flanges of this kind can tolerate temperatures of up to 870 degrees Celsius. ASTM A182 SS 321 Flanges can be welded using any conventional process, including submerged arc. Welding fillers such as AWS ER347 bare wire and E347 coated electrodes can be used. Flanges ASTM A182 SS 321 are easy to make and have reasonable machinability.

Stainless Steel 321H Flanges are not subject to weld decay (intergranular corrosion) when exposed to mildly corrosive environments. Stainless Steel 321 Slip-On Raised Flanges is a titanium stabilized chromium-nickel austenitic stainless steel with good strength and excellent corrosion resistance, as supplied in the annealed condition. Stainless Steel 321 Blind Raised Flanges is an excellent choice for various applications ranging from oil refinery equipment to automotive exhaust systems. Stainless Steel 321 Weld Neck Flanges can be readily formed and drawn, however, higher pressures are required and more spring-back is encountered than for carbon steel and ferrite stainless steels. Stress Relief – Heat this Stainless Steel 321 Flanges up to 700 ° C for 1 to 2 hours and air cool. Stainless Steel 321 Flanges contains 18 % chromium, 8 % nickel and a substantial addition of titanium. Stainless Steel 321 Flanges has comparable corrosion resistance and machinability to Stainless Steel 304. Stainless Steel 321 Flanges is not suitable for work at temperatures below 1700 ° F (927 ° C). Titanium is added to the composition of Stainless Steel 321H Flanges to suppress grain boundary chromium carbide precipitation and reduce susceptibility to intergranular corrosion.

The development of exhaust manifolds and expansion joints for aircraft are among the applications for ASME SA182 SS 321H Flanges. Heating system tubing, heat exchangers, and thermal oxidizers are made with ASTM A182 SS 321 Flanges because they have a high heat resistivity. Flanges are used in the production of medicinal and chemical equipment, as well as in the pulp and paper industry. Stainless steel SS 321H Flanges are used in a number of industries, including food preparation equipment, especially in chloride environments. ASTM A182 SS 321H Flanges are also used in pharmaceuticals, maritime applications, and architectural applications. They are widely used in a number of medical applications.
