High-carbon martensitic stainless steel 440C has trace amounts of silicon, manganese, and molybdenum along with roughly 16–18% chromium and 0.95–1.20% carbon. With a tensile strength of up to 760 MPa and outstanding resistance to wear and abrasion, it is well-known for its remarkable hardness and strength following heat treatment. It has a maximum Rockwell hardness of 60 HRC. It works well in mild conditions but is not as resistant to corrosion as austenitic grades. Because of these mechanical characteristics, 440C is appropriate for precision parts that need to be durable and long-lasting.
