Alloy Steel Fasteners are alloys of chromium-molybdenum and nickel. Sulphuric acid environments do not damage alloy steel fasteners. Many industries use alloy steel products due to their corrosion resistance. Chloride ion corrosion and pitting do not occur in alloy fasteners, thus causing no damage in such environments. Sulphuric acid contact does corrode alloy. Hence, sulphuric acid environment use does not damage these fasteners.
General corrosion, crevice corrosion and pitting does not occur in these super alloy fasteners. Sulphuric acid corrosion, nitric acid damage and chloride attacks do not cause harm to alloy fasteners. Alloy Steel is capable of withstanding a wide range of temperatures, without losing any of its mechanical properties. Molybdenum, copper and niobium is added to alloy steel, which stabilizes the structure of the alloy fasteners. Fasteners are available in four main types commercially i.e. bolts, screws, washers and nuts. Alloy Steel fasteners contain low amounts of carbon. Industries like power generation, chemical processing, pharmaceutical, food preparation and plastic preparation make extensive use of these fasteners. Forming is carried out with hot-cold and tradition methods. Carbide precipitation is minimal in alloy steel when welded.
