Request For Our Latest Prices On SS 440c Nuts in Mumbai, India!
The Mumbai, India-based Fasteners Mart is a prominent supplier and exporter of precision-engineered industrial fasteners catering to international industries. Among its high-end products is Stainless Steel 440C Nuts, which is fabricated from high-carbon martensitic stainless steel renowned for its superior hardness and wear resistance. The nuts are produced in numerous shapes such as hex, lock, and heavy-duty types with high strength and performance in severe conditions. Most suitable for uses requiring greater mechanical strength and abrasion resistance, 440C Nuts find extensive use in heavy-duty high-wear and high-load industrial assemblies.
Stainless Steel 440C Nuts consist of high carbon (0.95–1.20%), chromium (16–18%), manganese, silicon, and traces of molybdenum. These nuts have high hardness of up to 58–60 HRC when heat-treated. Their tensile strength is between 760–1000 MPa, with good wear resistance and moderate corrosion resistance in hardened condition. 440C nuts possess a density of around 7.75 g/cm³ and a melting range of 1480–1530°C. Although less corrosion-resistant than austenitic grades, they are well-suited where maximum strength and hardness are needed, particularly in tooling and mechanical applications.

440C Stainless Steel Nuts are utilized in situations requiring high strength, hardness, and wear resistance. They are frequently used in precision machinery, aerospace assemblies, tooling, and abrasion-resistant industrial equipment. They are also applied in bearings, valves, and other products where stress endurance is vital. The nuts are also favored when manufacturing cutting tools, molds, and dies and in pump and automotive systems. Though providing moderate resistance to corrosion, their true benefit is that they can withstand mechanical and thermal stress and remain intact.
