Alloy 20 Flanges Manufacturer, Supplier In Mumbai India

Alpha Overseas is well known in the industry for its production and distribution of Alloy 20 Flanges. Nickel and low carbon are present in the austenitic, niobium-stabilized alloy known as Alloy 20. Nickel, chromium, and iron will make up the majority of the chemical makeup of Alloy 20 Flanges, along with a few other elements like molybdenum and copper. Even in extreme chemical environments, the Alloy 20 Flanges are renowned for superior corrosion resistance. The Alloy 20 Pipe Flanges have excellent resistance qualities in environments containing phosphoric, sulfuric, and chloride acids. Even at high temperatures, the ASTM B462 UNS N08020 material is renowned for its solid mechanical characteristics.

Alloy 20 Flanges, Inconel 20 Flanges, Alloy 20 Weld Neck Flange, Nickel Alloy 20 Flange, Alloy 20Cb-3® Pipe Flanges, Incoloy Alloy 20 Flange, Carpenter 20 Flange, Alloy 20 Flanges Suppliers, UNS N08020 Slip On Flange, Alloy 20 Flanges Manufacturers in India.

Additionally, resistant to pitting and crevice corrosion in chloride and acidic medium is the ASTM B462 Flanges. The ASTM B462 Alloy 20 Blind Flanges are stabilized against sensitization by the niobium, which helps avoid intergranular corrosion. The 20cb3 Alloy 20 Slip-On Flanges have a high fabricability and are also quite resistant to stress corrosion cracking.

The SB 462 Material is well-liked in various industries due to its improved mechanical qualities. For instance, the chemical, pharmaceutical, and food processing sectors use the SB 462 Flange extensively. The plastic industries also highly demand the SB 462 UNS N08020. Manufacturers of Incoloy Alloy 20 Weld neck Flanges advise using them in systems like mixing tanks and heat exchangers, among other things. Due to their different chemical makeup and microstructure, Inconel Alloy 20 Socket Weld Flanges function exceptionally well. Alloy 20 flanges perform well at pretty high temperatures and are resistant to corrosion; they can keep their mechanical strength up to 1000°F. Columbium is used to support Alloy 20 flanges to reduce carbide precipitation during welding. Additionally, it provides as-welded intergranular corrosion resistance.

  • Alloy 20 flanges are essential for flue-gas desulfurization in power plants.
  • In moderately corrosive chemical processing environments, alloy 20 flanges are utilized to join heat exchangers, mixing tanks, metal cleaning equipment, pickling tanks and racks, and pipes.
