Weston Stainless, based in Midland, UK, is a reputable supplier of high-quality stainless steel products, providing durable and reliable solutions for various industrial applications. Their Stainless Steel 253MA Flanges are made from AISI 253 MA stainless steel, a high-temperature austenitic grade known for its excellent oxidation resistance, superior strength, and thermal stability. These flanges are available in various shapes, including weld neck, slip-on, blind, socket weld, and threaded flanges, making them suitable for petrochemical, power generation, cement, and furnace applications. With their exceptional mechanical properties and corrosion resistance, they ensure longevity in extreme heat environments.
Stainless Steel 253MA Flanges consist of 20-22% chromium, 10-12% nickel, 1.4-2.5% silicon, 0.05-0.10% carbon, 0.04-0.06% nitrogen, 0.8% manganese, 0.03% phosphorus, and 0.03% sulfur, providing high-temperature strength and resistance to oxidation. Their mechanical properties are tensile strength of 690 MPa, yield strength of 310 MPa, elongation of 40%, and hardness of 95 HRB, which makes them extremely durable. Physical properties include density of 7.8 g/cm³, melting point of 1425-1460°C, and thermal conductivity of 15 W/m·K, which qualify them for heavy-duty heat applications such as power plants and furnaces.
