Stainless Steel 446 Round Bar is a heat-resistant ferritic stainless steel grade with excellent scaling resistance at high temperatures. Known for its strong oxidation resistance and good corrosion resistance in many industrial environments, it performs well in both continuous and intermittent service conditions. Preston Pipes & Alloys, a leading Stainless Steel 446 Round Bar supplier, offers this grade with a balanced mix of elements like carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, and nitrogen, giving it strength and durability in demanding environments. With a density of 8.0 g/cm³ and a melting point of 1454 °C, it has impressive mechanical properties, including a tensile strength of 75,000 psi, yield strength of 30,000 psi, and elongation of 35%, making it a dependable choice for applications that demand high-temperature stability and mechanical performance.
We supply Stainless Steel 446 Round Bars in a wide range of specifications to match different industrial needs. The bars range in diameter from 3 mm to 800 mm and in thickness from 4 mm to 100 mm. It is produced in random, fixed, or cut lengths as required. Our manufacturing techniques include cold (bright) drawing, centreless grinding, hot rolling, and smooth turning to achieve the desired dimensional accuracy and finish. Surface finishes range from cold drawn and bright to sandblasted or hot rolled pickled, ensuring suitability for both functional and aesthetic purposes in various projects.
These bars are strong, resistant to oxidation, and corrosion in a variety of acidic and alkaline situations. It retains stability throughout thermal cycling and operates reliably in furnace parts, heat exchangers, kiln linings and boiler components. Their durability makes them a preferred material in petrochemical plants, power generation units, and other high-heat industrial operations. They are perfect for incinerator equipment and exhaust systems as they can withstand scaling at high temperatures.
Every ASTM A276 UNS S44600 Rod is subjected to stringent quality inspections to ensure compliance with ASTM A276, A479, and A182 standards. To assure service reliability, testing involves mechanical property verification, dimensional inspection and surface finish assessment. We pack them using industry-approved methods like wooden boxes, bundles, or protective wraps to prevent damage during storage and transport. This attention to detail guarantees customers receive products that are in good condition and ready for immediate usage. Get high-quality stainless steel bars with assured performance and timely delivery for your next project.
