Stainless Steel 253MA Flanges Manufacturer
Midland Alloys Inc. is a trusted Indian manufacturer and global supplier of stainless steel flanges, offering premium-grade products engineered for demanding industrial applications. Our 253MA stainless steel flanges are specifically designed for high-temperature environments and aggressive service conditions. Manufactured as per international standards such as ASTM A182 and ASME SA182, these flanges offer excellent strength, oxidation resistance and thermal stability. The chemical composition of UNS S30815 flanges includes 0.05–0.10% carbon, 0.80% max manganese, 1.40–2.00% silicon, 10.0–12.0% nickel, 20.0–22.0% chromium, and 0.03–0.08% cerium, with iron as the balance. These flanges possess a density of 8.0 g/cm³, melting point of 1320–1390 °C, tensile strength of 650 MPa, and yield strength of 300 MPa, with 35% elongation.PMI testing, spectro analysis, mechanical testing, macro and micro test and hardness checks are some of the methods we use to guarantee stringent quality control. Depending on the order and destination, wooden crates, pallets, boxes or carton packaging are used for safe packaging.
Benefits of Stainless Steel 253MA Flanges
253MA flanges deliver excellent reliability in elevated temperature environments and are ideal for harsh oxidising conditions. They provide a special set of metallurgical qualities that enable extended service life in demanding industrial setting.

Stainless Steel Flanges Grades We Offer
Difference Between Stainless Steel 253MA Flanges and Other Stainless Steel Flanges
253MA stainless steel flanges are designed specifically for high-temperature performance, unlike common austenitic grades like SS 304 or SS 316. High level of silicon, cerium and rare earth elements improve resistance to oxidation and creep. ASTM A182 253MA flanges maintain their mechanical integrity in oxidizing and carburising environments better than standard stainless grades. They have an advantage in applications above 1000 °C because they show creep rupture strength that is more in line with nickel-based alloys. Under such circumstances, other grades might lose stability or scale, but 253 MA flanges retain their strength and surface integrity over time.

Applications of ASTM A182 253MA Flanges
253MA stainless steel flanges find wide use in high-temperature industrial environments. In chemical processing plants, they withstand aggressive gas reactions. They sustain higher temperatures and pressures in digesters and bleaching towers used in the pulp and paper industries. Power plants install them in superheaters and exhaust ducts and the oil and gas industry uses them in reformer and cracker units. They are also utilized in the design of desalination plants, biofuel facilities, and exposed, heat-tolerant buildings. These flanges are also essential for food processing, cargo tanks, and marine equipment, particularly in areas with high levels of chloride or temperature fluctuations.
