Renowned for their remarkable hardness, strength, and resistance to corrosion, these circles are crafted using cutting-edge technology and high-quality materials. They’re perfect for precision engineering and high-stress applications. With outstanding wear resistance and dimensional stability, Stainless Steel 440C Circles are ideal for various industrial, mechanical, and tooling environments. Victor Sheets and Plates guarantees that every product adheres to international quality standards, delivering durable and high-performance stainless steel solutions across multiple engineering and manufacturing sectors.
Stainless Steel 440C Circles are made up of iron, chromium (16–18%), carbon (0.95–1.20%), along with small amounts of manganese, silicon, and molybdenum. This high-carbon martensitic stainless steel is known for its impressive hardness and edge retention after heat treatment. It boasts a tensile strength of around 760 MPa (when annealed) and can reach up to 1900 MPa (when hardened), along with solid wear and corrosion resistance. While it may be less ductile than other stainless grades, 440C excels in dimensional stability, toughness, and strength, making it a great choice for applications that demand high hardness and precision in tough conditions.
