Aditya Stainless stands out as a top manufacturer and supplier of Stainless Steel 253MA Tubing in Kolkata, India. They provide high-performance tubing solutions that excel in extreme temperatures and oxidizing environments. SS 253MA (UNS S30815) is a heat-resistant austenitic stainless steel, enriched with nickel, chromium, silicon, and nitrogen, crafted for remarkable strength and oxidation resistance at temperatures soaring up to 1150°C. These tubes are perfect for use in furnace components, heat exchangers, kilns, and petrochemical plants. With outstanding creep strength, thermal stability, and scaling resistance, 253MA tubing is a dependable option for high-temperature applications in both oxidizing and reducing conditions.
Stainless Steel 253MA Tubing is made up of about 21% chromium, 11% nickel, 1.7% silicon, along with small amounts of nitrogen and rare earth metals that boost its high-temperature oxidation resistance and strength. It boasts a tensile strength of at least 600 MPa, a yield strength of 310 MPa or more, and an elongation of around 40% at room temperature. Even at elevated temperatures, 253MA shows excellent creep resistance and maintains its structural integrity, making it perfect for thermal cycling. It also offers good corrosion resistance in oxidizing environments and outperforms standard austenitic stainless steels like 304 or 316 in terms of scaling resistance.
