The Stainless Steel 440C Fasteners produced by Adam Stainless in Canberra, Australia, are crafted from a high-carbon martensitic stainless steel alloy, celebrated for its remarkable hardness and strength. Typically, the composition includes 16–18% chromium, 0.95–1.20% carbon, along with trace amounts of manganese and molybdenum. These fasteners can achieve a tensile strength of up to 760 MPa and exhibit excellent wear resistance following heat treatment. While they may not be as corrosion-resistant as austenitic grades, 440C fasteners still deliver dependable performance in mildly corrosive settings. They are magnetic and well-suited for applications where strength, sharp edges, and longevity are paramount.
