Neil Metals, being a Kolkata-based supplier and manufacturer, specializes in the production of premium **Stainless Steel 253MA Hex Bars and Rods** according to international standards such as UNS S30815 and ASTM A240. Constructed through precision forging and stringent quality-controls, their items provide superior oxidation resistance to 1150 °C and excellent creep strength in austenitic conditions. Used in sectors like power generation, petrochemical, metallurgy, and industrial furnace manufacturers, Neil Metals provides reliable supply, technical assistance, and timely delivery of 253MA bars and rods customized to improve industrial efficiency.
**Stainless Steel 253MA Hex Bars and Rods** have 20–22% chromium, 10–12% nickel, 1.4–2.0% silicon, and 0.14–0.20% nitrogen, trace cerium (0.03–0.08%), and low carbon, manganese, and sulfur content. The lean austenitic alloy features tensile strength between 550–750 MPa, yield strength of 250–350 MPa, elongation of 40–50%, and high impact toughness even at cryogenic temperatures ([metalzenith.com][1]). The alloy exhibits weldability, formability, high-temperature creep, and oxidation resistance, suitable for precision-engineered hex-shaped parts.

**Stainless Steel 253MA Hex Bars and Rods** find their application in high-temperature industrial processes. They are employed to make burner nozzles, radiant tubes, and heat exchanger components, kilns, and industrial furnace components, providing superior oxidation resistance in carbon-rich environments. In refinery and petrochemical operations, they are tube hangers, expansion bellows, and mechanical components in furnaces. Their durability up to 1150 °C and machinability render them irreplaceable in power plants, cement kilns, and metallurgical processing machinery where shape accuracy, thermal stability, and durability are of utmost importance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
