Stainless Steel 440C is a high-carbon, martensitic stainless steel that contains around 16–18% chromium and 0.95–1.20% carbon, along with trace amounts of manganese and molybdenum. It boasts remarkable hardness, strength, and wear resistance. After undergoing heat treatment, 440C can reach a Rockwell hardness of up to 60 HRC. Its mechanical properties typically feature a tensile strength ranging from 760 to 1050 MPa and good fatigue resistance. While it offers moderate corrosion resistance, it truly shines in applications that require high strength and excellent edge retention, making 440C perfect for cutting tools, bearings, and high-precision components.

Stainless Steel 440C Hex Bars find extensive use in applications that require high hardness, wear resistance, and dimensional stability. They are commonly utilized in industries like aerospace, automotive, surgical instruments, and tooling. These hex bars are perfect for crafting ball bearings, valve components, knife blades, gauges, dies, and high-performance mechanical parts. Thanks to their superb edge retention and smooth surface finish after machining, 440C hex bars are also favored in the production of precision instruments and molds. While they may not be ideal for highly corrosive environments, they perform admirably in dry or mildly corrosive settings.
