At Hazlewood Fasteners, we specialize in manufacturing and supplying Stainless Steel 440C Nuts in Canberra, Australia—built for extreme strength, wear resistance, and precision. Made from the hardest and most durable stainless grade, 440C, these nuts are designed to perform reliably in demanding industrial, mechanical, and high-stress applications. Their superior hardness and ability to resist corrosion and deformation make them ideal for critical fastening operations. At Hazlewood Fasteners, we combine precision engineering, quality control, and advanced material technology to ensure every 440C nut provides lasting performance under pressure, temperature, and time.
Stainless Steel 440C Nuts are high-carbon martensitic stainless steel composed of approximately 16–18% chromium, 0.95–1.20% carbon, and minor amounts of manganese, silicon, and molybdenum. This composition allows the material to achieve exceptional hardness—up to Rockwell C 58—after heat treatment. It offers a tensile strength exceeding 760 MPa, along with excellent wear and corrosion resistance. 440C maintains its strength and dimensional stability even at elevated temperatures, making it suitable for precision parts and heavy-duty assemblies. Its combination of hardness and corrosion resistance sets it apart from standard stainless grades.
