Stainless Steel 440C is a high-carbon martensitic stainless steel that contains about 16–18% chromium and 0.95–1.20% carbon, making it one of the hardest stainless steels on the market. It can be heat-treated to achieve remarkable hardness, typically reaching up to 58–60 HRC. Its tensile strength varies from 760 to 1900 MPa, depending on the heat treatment process, and it boasts excellent wear and abrasion resistance. While it offers moderate corrosion resistance, 440C truly shines in applications that demand superior mechanical strength, dimensional stability, and resistance to deformation under stress, making it perfect for precision components and cutting tools.
