Amer Stainless, based in Amman, Jordan, is a trusted manufacturer and supplier of high-performance Stainless Steel 442 Bolts, designed to deliver exceptional strength and heat resistance in tough industrial settings. These bolts are meticulously crafted using advanced forging and machining techniques, which guarantee impressive dimensional accuracy, durability, and a long lifespan. Stainless Steel 442 is renowned for its outstanding resistance to oxidation and scaling at high temperatures, making it perfect for situations involving thermal and mechanical stress. Amer Stainless adheres to rigorous global quality standards, offering reliable fastening solutions for sectors like power generation, petrochemicals, furnace equipment, and heat-treatment systems.
The Stainless Steel 442 Bolts are made from a high-chromium martensitic alloy that contains 18–23% chromium, along with moderate carbon levels and trace amounts of molybdenum, manganese, and silicon. This alloy provides excellent heat resistance, high tensile strength, and impressive hardness when heat-treated. SS 442 stands out for its superior oxidation and scaling resistance at elevated temperatures while maintaining structural integrity. Its mechanical properties include good wear resistance, high creep strength, and dependable performance during thermal cycling. While its ductility may not match that of austenitic grades, its strength and heat stability make it an excellent choice for high-temperature fastening applications.
