Custom 455 Round Bars are premium stainless steel alloy bars manufactured to deliver high strength, excellent corrosion resistance, and superior mechanical performance in demanding applications. As a reliable manufacturer, supplier, and exporter, we offer Custom 455 Round Bars in a variety of sizes and finishes to suit diverse industrial needs. These bars are produced through advanced processing methods that ensure precise dimensions, excellent surface finish, and consistent material quality. Available in diameters ranging from 6mm to 200mm, and customizable in length, these round bars are offered in centerless ground, bright, black, and polished finishes. Conforming to international standards like ASTM A276, ASTM A479, and ASME SA276, they meet global industry specifications with high reliability and performance.
Technically, Custom 455 Round Bars are known for their high tensile strength (up to 1100 MPa), superior fatigue resistance, and excellent resistance to stress corrosion cracking and oxidation. The alloy contains a balanced mix of chromium, nickel, and other elements that enhance its durability in both high-pressure and corrosive environments. These mechanical properties, combined with good formability and weldability, make the bars ideal for manufacturing precision components that are exposed to mechanical and thermal stress. They are frequently used in critical sectors such as aerospace, automotive, power generation, chemical processing, marine, and general engineering—especially in components like shafts, fasteners, valves, and structural parts.
The key benefits of using Custom 455 Round Bars include long service life, reduced maintenance needs, and superior performance under extreme conditions. These bars are designed to maintain their integrity even in challenging environments, offering resistance to pitting, fatigue, and wear. Their versatility and reliability make them suitable for both static and dynamic applications. Whether for use in high-temperature turbines, corrosive marine equipment, or precision-engineered aerospace components, Custom 455 Round Bars provide the strength, durability, and performance that modern industries demand.
Custom 455 Round Bars offered in Hot Rolled, Cold Drawn, Centerless Ground, Peeled, Polished, Bright, and Forged finishes – Wide range of sizes and shapes in stock.
