Our Certifications
Steel sales co is one of the most reliable supplier, manufacturer, stockiest, as well as distributor of alloy 20 pipe fittings since years. Based in Mumbai, India. delivering materials and products in every possible part of the country to fulfill requirements of our clients in the field of metals and alloys on a wide range since years. At Steel sales co we use premium quality raw material and some of the most advanced technology and machineries available to manufacture and process all the products. Every product and material here is handled by skilled and trained staff and inspected by highly experienced quality inspectors.
alloy 20 pipe fittings are developed mainly for applications which involves sulfuric acid. alloy 20 is considered to be chloride ion corrosion as well as pitting resistant. Its copper content plays a remarkable role in protecting the alloy from sulphuric acid. Alloy 20 is preferably used solve problems related to stress corrosion cracking. Designation Cb-3 indicates columbium / niobium stabilization in alloy with the same name. alloy 20 is also known by other names such as: UNS N08020, DIN 2.4660, CN7M, carpenter 20 CB-3, AL 20, Carlson alloy C20, Nickelvac 23, VDM alloy 20 also known as Nicofer 3620 Nb.
Alloy 20 has a wide range application in production of plastic and synthetic fibers, chemical and petroleum processing equipment, process piping, mixing tanks, heat exchangers, petrochemical and refining, marine, pharmaceutical and food processing, storage tanks, agitators, pump and valve parts, fasteners and fittings, synthetic rubber manufacturing equipment bubble caps, dye production, acid cleaning equipment, pickling equipment etc.
Alloy 20 can also be made available in various forms like sheets, bar, plate, pipe, tubes, welding wire (AWS classifications: ER320LR and E320LR- 16) and also in fittings such as flanges, slip-ons, blinds, weld necks, lapjoints, long welding necks, socket welds, stub-ends, returns, reducers, pipe nipples, caps, crosses, tees and elbows.
We also pass all our products and material from various tests like hardness test, flattening test, flaring test, pitting resistance test, micro and macro test, PMI testing that stands for positive material identification, IGC test (intergranular corrosion test), hydrostatic test, hydrogen- induced cracking (HIC) test, radiography test and many similar tests.
