Amer Stainless, based in Amman, Jordan, is a reputable manufacturer and supplier of top-notch Stainless Steel 446 Bolts, designed to excel in high-temperature and highly corrosive settings. These bolts are crafted using cutting-edge forging and machining techniques, which guarantee precision, durability, and structural integrity. SS 446 is celebrated for its outstanding resistance to oxidation and scaling, making these bolts perfect for tough industrial environments. Amer Stainless follows rigorous international quality standards, providing dependable fastening solutions for sectors like petrochemical, furnace equipment, thermal processing, power generation, and chemical plants, where strength and heat resistance are essential.
Stainless Steel 446 Bolts are composed of a high-chromium ferritic alloy that contains 23–27% chromium, along with low carbon content and trace amounts of molybdenum and silicon. This unique blend offers remarkable resistance to oxidation, scaling, and sulfidation at high temperatures. The alloy boasts good tensile strength, moderate hardness, and exceptional thermal stability. Its mechanical properties include high resistance to creep, thermal shock, and warping under extreme conditions. While it may not be highly ductile, SS 446 delivers excellent performance in high-temperature applications, making it a reliable choice for fastening components that face intense heat and corrosive environments.
