Ganpat Industrial Corporation offers an exceptional array of Alloy 20 Pipe Flanges, where our entire product range ensures impeccable finishing and is performance based. These Alloy 20 Pipe Flanges (UNS N08020) is stabilized with Columbium to minimize carbide precipitation during welding. Alloy 20Slip On Flanges particularly excels in resisting corrosion to hot sulfuric acids when compared to conventional stainless steels such as 316. These Alloy 20 Weld Neck Flanges has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. Alloy 20 Spectacle Blind Flanges resists pitting and chloride ion corrosion and its copper content protects it from sulfuric acid. Meanwhile, Alloy 20 Threaded Flanges are also being offered in different sizes and shapes to our customers, where we also offer the same at best prices. Welding of these Alloy 20 Socket Weld Flanges is commonly performed via, TIG, MIG as well as submerged arc welding (SAW) using either the matching filler metal, ER320LR for TIG and MIG and E320LR for SAW. There has long been a debate on whether Alloy 20 Lap Joint Flanges is a stainless steel or a nickel alloy because the nickel content is right on the border of defining it as one way or the other. So, depending on who you talk to this alloy may be referred to as these Alloy 20 Ring Joint Type Flanges or as a nickel alloy.
Alloy 20 is an austenitic stainless steel with less than 50 percent iron that was developed for sulfuric acid uses. It is used in various applications in the chemical, and petrochemical industry, power generation, and plastics sectors due to its superior corrosion resistance.
