Alpha Overseas(AOS) is one of the distinguished manufacturers that offer Alloy 20 Fasteners, which is steadied by means of Columbium to minimalize carbide precipitation in the course fusing. Carpenter 20 Fasteners is often used in chemical and petroleum processing equipment. By means of the soaring content of nickel, Alloy 20 Stud Bolts shows excellent confrontation to chloride - persuaded SCC. Alloy 20 Screws is a resolution for SCC which can happen when steel is familiarized to chloride solutions. Alloy 20 Washers chiefly shines in counterattacking erosion to hot sulphuric acids when related to conservative alloys like SS 316. Alloy 20 Bolts as well has first - rate mechanical features at both high and ambient heats. The nickel, copper, chromium and molybdenum stages of Alloy 20 Nuts offer outstanding wide-ranging erosion resistance. Alloy 20 Stud Bolts is austenitic nickel – iron – chromium steel that provides our customers an extensive range of advantages which include: outstanding confrontation to erosion, crevice erosion and pitting. Alloy 20 Screws is utilized in several uses like flue - gas desulfurization, food dispensation, chemical processing, storage, and pharmaceutical uses.
