253 MA [S30815] Tubes, commonly referred to by its universal designation UNS S30815, constitutes a highly performance-driven type of austenitic stainless steel tubing specimen that has an application predominantly in higher temperature-embarked settings and those with an oxidizing nature. These tubes are fit by manufacture as per foreign standards such as ASTM A213 and ASTM A312 specifications and are commonly used in industries which necessitate the use of materials which are highly mechanically, oxidation and environmentally resistant and have a long life span of usage in excessively hot environments.
We are one of the most prominent manufacturers and suppliers of the 253 MA Tubes at Hindco Steel And Alloys that deal with manufacturing and supplying high-quality and reliable tubing solutions with references to the requirements of the global industries. Design involving balanced mixing of a combination of chromium, nickel and the rare earth metals such as cerium, 253 MA has great structural stability and creep rupture strength of the limit of 1150 o C. Presence of a limited amount of nitrogen in the alloy increases tensile strength and welding of the alloy.
The fact that it resists oxidation and carburization, especially with high temperatures, makes it suitable in heat exchangers, kilns, recuperators, and other varieties in the petrochemical, refinery and thermal processing sectors. All our 253 MA Tubes are produced with high quality measures and satisfy ASTM A213/A312 requirements to match the best world criteria in terms of performance and reliability. Our customized length, thickness and diameter offer tubes in both seamless and welded tubes per the requirements of the clients.
All the tubes are put under serious non-destructive tests (NDT), intergranular corrosion test (IGC), and hydrostatic test to confirm the accuracy of dimensions and defect-free performance. If you are looking for high-temperature resistant, corrosion-proof, and long-lasting tubing solutions, Hindco Steel And Alloys is your ideal partner.
