Piyush Steel is a popular manufacturer, stockiest, supplier, and distributor of Alloy 20 Tubes. Alloy 20 is an austenitic alloy consisting of chromium, nickel, and iron as its base elements. These alloy 20 tubes have an excellent corrosion resistance in chemical environments containing sulfuric acid and many other aggressive media. This alloy is generally stabilized by niobium to resist intergranular corrosion. Alloy 20 tubes are designed to provide potential cost savings while out performing standard stainless steels. Alloy 20 tubes are used in a wide variety of industries, including chemical processing, marine, petrochemical and refining, pharmaceutical and food processing. End use applications of our alloy 20 tubes includes mixing tanks, agitators, storage tanks, pump and valve parts, food processing equipment, fasteners and fittings. These tubes are used for applications which are limited to a maximum temperature of 1000 degree F. Alloy 20 tubes have great resistance to sulfuric acid. This alloy also exhibits good resistance in nitric acid, phosphoric acid and aqueous salt solutions.
Our Alloy 20 tubes are an excellent choice when chloride stress corrosion cracking is a problem, because it resists pitting and crevice corrosion. Our Alloy 20 Tubes have many different industrial applications which include Marine, Power, Chemical processing, Pollution control, Paper processing, Waste disposal, etc. The melting point of these tubes is 1443 degree Celsius whereas its elongation is 45 %. The mechanical properties of these Alloy 20 Tubes are they have tensile strength of Psi – 80,000, MPa – 551 and yield strength of Psi – 35000, MPa – 241. We perform a number of tests on our tubes to ensure high standard quality. The tests conducted are eddy current testing, hydrostatic testing or ultrasonic examination, NDT and also chemical and physical property inspection. Some of the other tests are chemical analysis, Mechanical test, Rockwell hardness test, chemical test, intergranular corrosion test, positive material test, flattening test, flaring test, and third-party inspection and so on. Our highly qualified team of professionals strive hard to meet our customers’ needs and have thus received acclamations. Customer satisfaction is our prime goal and we strive to meet the same.
