Weston Stainless, which is located in Midland, UK, is a reliable source of high-grade stainless steel products to construction, aerospace, and manufacturing industries. Among its high-end products, Stainless Steel 253Ma Tubing finds special appreciation for its superior high-temperature strength and resistance to oxidation. Produced in Grade 253Ma, this tubing can come in different shapes and sizes, such as round, square, and rectangular shapes, for accommodating different industrial needs. Produced from high–chromium, nickel, and silicon-containing heat-resistant austenitic stainless steel, 253Ma tubing provides superior mechanical performance and durability and is best suited for furnace parts, heat exchangers, and severe thermal conditions.
Stainless Steel 253Ma Tubing contains Chromium (20-22%), Nickel (10-12%), Silicon (1.4-2%), Nitrogen (0.14-0.2%), Carbon (0.05-0.10%), and minor amounts of Cerium for improved oxidation resistance. It has a tensile strength of ≥600 MPa, yield strength of ≥310 MPa, and elongation of ≥40%, providing superior endurance in high-temperature conditions. The physical characteristics are a density of 7.8 g/cm³, thermal conductivity of 15 W/m·K, and a melting point of about 1420°C. These characteristics render 253Ma tubing as the best for use in extreme temperature applications where high strength, oxidation resistance, and structural integrity are needed.
