Brian Fasteners, based in Houston, USA, stands out as a top manufacturer and supplier of precision-engineered industrial fasteners, including their high-performance Stainless Steel 440C Nuts. They’ve built a solid reputation for their dedication to quality, durability, and keeping customers happy, ensuring that their products meet the toughest industry standards. With cutting-edge manufacturing methods and rigorous quality checks, Brian Fasteners provides Stainless Steel 440C Nuts designed for critical applications in sectors like aerospace, automotive, defense, and tooling. These robust, wear-resistant fasteners are crafted for challenging environments where hardness, corrosion resistance, and dimensional stability are crucial for dependable, long-lasting performance.
Stainless Steel 440C Nuts are crafted from a high-carbon martensitic stainless steel alloy that contains about 16–18% chromium and 0.95–1.20% carbon. This unique blend gives them impressive hardness, wear resistance, and decent corrosion resistance. After undergoing the right heat treatment, 440C can achieve a tensile strength of up to 760 MPa and a yield strength around 450 MPa, with hardness levels reaching up to 58 HRC. While it may not be as corrosion-resistant as austenitic grades, 440C shines in applications that demand high strength, precise dimensions, and abrasion resistance, making it perfect for mechanical systems, tooling, and high-load assemblies.
