Alloy Steel Circles are expertly crafted, high-strength steel products tailored for applications that demand outstanding mechanical properties, durability, and wear resistance. Made from specially formulated alloyed steel grades, these circles offer remarkable toughness, hardness, and reliability, even in the toughest industrial and structural environments. You’ll find Alloy Steel Circles in machinery, automotive, and engineering sectors, where components need to endure high stress, impact, and fatigue. With their precise dimensions, smooth surface finish, and consistent quality, they’re perfect for creating flanges, gears, rings, and structural components that require long-lasting performance and resilience in challenging operational settings.
These circles are made from iron, enhanced with controlled amounts of chromium, nickel, molybdenum, and other alloying elements to boost strength, hardness, and wear resistance. Their mechanical properties typically feature a tensile strength ranging from 600 to 900 MPa, yield strength between 350 and 600 MPa, and good elongation, depending on the specific grade. Heat treatment can further improve hardness, toughness, and fatigue resistance, making them suitable for high-performance applications. The blend of strength, toughness, and dimensional stability ensures that Alloy Steel Circles meet the rigorous demands of industrial and structural use.
