Austenitic stainless steel forged rings,hollow bars 316L/904L

Characteristics Monel 400 (UNS N04400) is a nickel-copper alloy designed for corrosion resistance in a wide range of harsh environments. Its high nickel and copper content ensures good corrosion resistance, especially in seawater and other corrosive media. Excellent corrosion resistance Monel 400 offers excellent resistance to a wide range of acids, alkalis and brines, especially in marine environments and chemical processing. Good mechanical properties The alloy offers good strength and toughness at both high and low temperatures, ensuring reliability in a wide range of engineering applications. Resistance to chloride stress corrosion cracking Monel 400 has good resistance to chloride-induced stress corrosion cracking, making it suitable for chemical and marine applications. Easy to weld and process Monel 400 can be processed through a variety of welding processes, making it suitable for the manufacture of complex shaped components.

Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance. With its highly alloyed chemistry — 25% nickel and 4.5% molybdenum, 904L provides good chloride stress corrosion cracking resistance, pitting and general corrosion resistance superior to 316L and 317L molybdenum enhanced stainless steels.Alloy 904L was originally developed to withstand environments containing dilute sulfuric acid. It also offers good resistance to other inorganic acids such as hot phosphoric acid as well as most organic acids.Alloy 904L is easily welded and processed by standard shop fabrication practices.
