Stainless Steel 440C Circle is a high-carbon martensitic stainless steel primarily made up of iron, chromium (16–18%), and carbon (0.95–1.20%), along with trace amounts of manganese, silicon, and molybdenum. It boasts impressive mechanical properties, including hardness levels reaching up to 60 HRC, high tensile strength, excellent edge retention, and outstanding wear resistance. While its corrosion resistance isn’t as high as that of austenitic grades, it still performs admirably in mildly corrosive environments, making it a great fit for demanding applications that require both strength and toughness.
