Stainless steel 440C is a high-carbon martensitic stainless steel. It has a high wear and corrosion resistance, and is able to be hardened to a higher strength than other stainless steels. It is commonly used for knife blades, bearings, and other high-stress applications. It is magnetic and can be heat treated to achieve a range of mechanical properties.
