Amer Stainless, a top-notch manufacturer and supplier located in Amman, Jordan, specializes in high-performance Stainless Steel 440B Fasteners designed for applications that demand outstanding hardness, strength, and wear resistance. These fasteners are crafted using cutting-edge processing techniques and rigorous quality control measures, ensuring they deliver exceptional durability, precise dimensional tolerances, and a long lifespan. Amer Stainless offers a variety of 440B fasteners, including bolts, nuts, screws, washers, and threaded components, all tailored for tough industrial settings. Renowned for their reliability and consistent performance, 440B fasteners from Amer Stainless are perfect for a wide array of mechanical, structural, and precision engineering applications both in Jordan and around the globe.
Stainless Steel 440B Fasteners are composed of high-carbon martensitic stainless steel, featuring chromium (16–18%), carbon (0.75–0.95%), along with small amounts of manganese, silicon, and molybdenum. This unique blend grants them excellent hardenability, high wear resistance, and remarkable mechanical strength. After undergoing heat treatment, 440B fasteners reach impressive hardness levels while still maintaining good edge retention and stability under stress. They also provide moderate corrosion resistance in controlled environments. These mechanical and chemical properties make 440B fasteners an ideal choice for precision fastening solutions in high-load and abrasive conditions.
