Detailed Information

Prashaant Steel & Alloys is a well-known maker and retailer of Valves for Stainless Steel 321 in the market. We produce ASME SA182 SS 321H Valves that follow global and national quality requirements by using the best quality raw materials. The ASTM A182 SS 321 Valves 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 Valves are produced to have improved performance at low temperatures. Valves of this kind can tolerate temperatures of up to 870 degrees Celsius. The ASTM A182 SS 321 Valves 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 Valves. We manufacture and sell a wide range of ASTM A182 SS 321 Valves. ASME SA182 SS 321H Valves preserve strength and corrosion resistance even when exposed to high temperatures. Valves of this kind can tolerate temperatures of up to 870 degrees Celsius. ASTM A182 SS 321 Valves 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. Valves ASTM A182 SS 321 are easy to make and have reasonable machinability.

These instrumentation ball valves are formed with Stainless Steel 321 / 321H alloy that is a stabilized austenitic steel alloy combined with 18% of chromium and 8 % of nickel content. In addition to it includes titanium content that offers good resistance to general corrosion. These valves resist good oxidation up to 1500 degree F whereas offers good stress rupture and creep properties as compared to other alloys. Furthermore, it possesses good low-temperature toughness also. These valves also consider high carbon content that enhances excellent tensile strength and creeps resistance at a temperature range of 1000 degrees F.

The valves are stabilized against chromium carbide formation due to the titanium content. Furthermore, in hydrocarbon services, these resists polythionic acid stress corrosion cracking and also utilized in fluoride-free caustic or chlorides solutions at moderate temperatures. These ball valves are easily formed and possess good ductility. The hardness of these valves are not achieved by heat treatment, therefore, these are only cold worked. By means of standard shop fabrication practices, these are easily welded and fabricated.

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