Detailed Information

Prashaant Steel & Alloys is a maker of 310H Stainless Steel Flanges of exceptional quality. The SS UNS S31009 Flanges that we manufacture are highly common due to their superior quality. Prashaant Steel & Alloys has a production facility that is well-equipped with cutting-edge technology, allowing us to manufacture industry-recognized ASTM A182 SS 310H Flanges. We believe in customer loyalty at Prashaant Steel, and we aim to satisfy our customers’ expectations and demands in terms of both quality and quantity. Our wide inventory allows us to easily meet bulk orders for our customers. We export our goods to countries all over the world, and we store our UNS S31009 SS Flanges in durable wooden boxes to prevent loss during transit. Many of the required documentation are also included in our packaging. Raw Materials Stamp, 100% Radiography Examination Report, Third Party Inspection Report, and other records are included with our SS 310H Flanges. Mechanical tests, pitting resistance tests, flaring tests, flattening tests, bent tests, positive content recognition tests, intergranular corrosion tests, and micro and macro tests are some of the relevant tests performed on Stainless Steel 310H Flanges. They’re dependable, and upkeep isn’t prohibitively costly. The joining of two or three pipes is a common procedure. The SS UNS S31009 Flanges are used to secure the end of a pipe. They have a stunning finish with flat corners. Their height is moderate and tolerable. Customers will be able to purchase these Stainless Steel 310H Flanges at affordable prices, as well as in a range of shapes, sizes, and thicknesses.

Flanges are commonly used in various pipe systems to connect straight or tube segment pipes. Stainless Steel 310H Flanges have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in sub-zero environments. The high chromium content – intended to increase high-temperature properties – also gives these Stainless Steel 310H Threaded Flanges good aqueous corrosion resistance. Sea water-resistance of our Stainless Steel UNS S31009 Flanges is about 22 Degree C, which is similar to that of Grade 316. In high-temperature service, these Stainless Steel 310H Blind Flanges exhibit good resistance to oxidizing and carburizing atmospheres. Our Stainless Steel 310H Flanges resist fuming nitric acid at room temperature and fused nitrates up to 425 Degree C. The high carbon contents do make these Stainless Steel 310H Flanges susceptible to sensitization and hence intergranular corrosion after elevated temperature exposure or welding. Our Stainless Steel 310H Flanges are often produced in “Dual Certified” form – mainly in plate and pipe, which as well have chemical and mechanical properties.

310H Flange is used in industries such as food processing machinery, especially in the production of wine and beer brewing. Chemical tubes, including those for storage, are made of Stainless Steel 310H Flanges. Stainless Steel 310H Flanges are also used in the manufacturing of kitchen machines and appliances. 310H Flanges of Stainless Steel are also used to produce threaded fasteners.

To maintain the quality specifications of UNS S31009 SS Flanges, Prashaant Steel & Alloys issues documentation such as fumigation certificates, raw materials certificates, inventory traceability reports, and so on. Both orders are delivered in compliance with the needs of the customers. To ensure only high-quality outputs, we at Prashaant Steel & Alloys perform extreme quality tests. Hardness test, flattening test, mechanical testing such as area tensile, etc. are some of the tests we perform on SS 310H Flanges.
