Alpha Overseas is one of the well - known manufacturers that offer Stainless Steel 904L Fasteners, which is a non - steadied austenitic alloy by means of low content of carbon. SS 904L Screws is generally utilized in Seawater dispensation, Desalination plants and Flue gas cleaning. SS 904L Washers has extremely first - rate confrontation to pitting erosion, SCC and a much improved confrontation to fissure rust than steels of 304L and 316L. SS 904L Bolts is characteristically utilized in chemical manufacturing for unadorned erosion atmospheres, which is improved confrontation to pitting and stress corrosion cracking. The high chromium and nickel content of SS 904L Nuts make it erosion resilient in both rusting and plummeting atmospheres. Stainless Steel 904L Stud Bolts is used lengthily in chemical process manufacturing together with the manufacture of phosphate - based manures. The adding of copper content to Stainless Steel 904L Screws offers it erosion resilient features higher to the conservative chrome and nickel alloys, especially to phosphoric acids, sulphuric acids and acetic acids. Stainless Steel 904L Washers, well – thought – out as soaring alloy steel, is accumulated by means of copper to increase its confrontation to sturdy plummeting acids, like sulphuric acid.
