Nascent Pipe & Tubes is a leading manufacturer and exporter of 253 MA Tubes with UNS number S30815, engineered to meet the high-performance demands of extreme environments. These tubes are manufactured in strict accordance with ASTM standards including ASTM A213 and ASTM A312, which ensure dimensional accuracy, mechanical strength, and corrosion resistance. The universal standard name of the material is Alloy 253 MA, a high-temperature austenitic stainless steel known for excellent oxidation resistance and superior mechanical properties even at elevated temperatures up to 1150°C.
At Nascent Pipe & Tubes, our UNS S30815 Tubes are manufactured using advanced technology and premium quality raw materials that comply with international norms. These tubes are particularly suitable for use in petrochemical plants, power stations, furnaces, and waste incineration plants due to their ability to withstand thermal fatigue and creep deformation. The high chromium (21%) and nitrogen content enhances the oxidation and creep resistance, while the addition of rare earth metals improves the scaling resistance.
