Alloy 20 Rods Manufacturers, Alloy 20 Sheet Exporters, Alloy 20 Round Bars, Alloy 20 Bars Suppliers in India.
Durabay Inc Company is one of the prominent wholesaler and dealer of Alloy 20 Round Bars , which contains niobium for stabilization against sensitization and resultant intergranular corrosion. Resistance to sulphuric acid is particularly exceptional but the alloy shows useful resistance in phosphoric acid, nitric acid as well as in chloride environments.
Alloy 20 Flat Bars ofDurabay IncCompany has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulphuric, phosphoric, and nitric acids. At thirty-three percent of nickel, Alloy has practical immunity to chloride stress corrosion cracking. This alloy is often chosen to solve SCC problems, which may occur with 316L stainless.
Alloy 20 Hex Bars ofDurabay IncCompany can be used for a wide variety of applications including: control valves, pressure relief valves, and centrifugal pumps. It was designed for maximum resistance to acid attack and demonstrates superior resistance to stress-corrosion cracking in boiling twenty percent to forty percent of sulphuric acid, and also has excellent general corrosion resistance to sulphuric acid and to chloride stress corrosion cracking.
Alloy 20 Sheets ofDurabay IncCompany has good mechanical properties at both ambient and elevated temperatures, up to approximately 930 Degree F (500 Degree C) and is readily fabricated by usual industrial processes. It combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Alloy 20 Plates is composed of carbon, chromium, copper, iron, manganese, molybdenum, nickel, phosphorous, silicon, and sulphur.
