Malik Fasteners is a top-notch manufacturer and supplier based in Manama, Bahrain, specializing in high-quality Stainless Steel 347 Washers that are built to excel in tough industrial settings. These washers are crafted with precision and adhere to international standards, ensuring they deliver outstanding durability, corrosion resistance, and precise dimensions. The use of Stainless Steel 347, which is stabilized with niobium, enhances its resistance to intergranular corrosion and helps maintain its mechanical strength even at high temperatures. Malik Fasteners caters to various industries, including petrochemical, chemical processing, power generation, and manufacturing, providing washers that ensure reliable load distribution, long-lasting fastening stability, and exceptional performance in high-temperature and chemically aggressive environments.
Stainless Steel 347 Washers are made up of chromium (17–19%), nickel (9–13%), and niobium, which stabilizes the alloy and prevents carbide precipitation during welding or exposure to high temperatures. This composition gives the washers excellent resistance to intergranular corrosion and oxidation. On the mechanical side, SS 347 washers boast high tensile strength, good yield strength, and impressive toughness, making them stable under both mechanical and thermal stress. Their ability to resist creep and their overall durability make them a trustworthy choice for continuous use in elevated temperatures. The blend of corrosion resistance, high-temperature strength, and toughness guarantees reliable performance in demanding industrial conditions.
