015Cr21Ni26Mo5Cu2


015Cr21Ni26Mo5Cu2 is a high-alloy austenitic stainless steel with low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for harsh corrosive environment. It has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride clearance corrosion and stress corrosion cracking, and is not prone to corrosion spots and cracks. Its pitting resistance is slightly better than other steel grades. It has good machinability and weldability, and can be used for pressure vessels. Widely used in petroleum and petrochemical equipment, such as reactors in petrochemical equipment, sulfuric acid storage and transportation equipment, such as heat exchangers, and power plant flue gas desulfurization devices. The main parts of use are: the tower body, flue, door baffle, internals, and spray system of the absorption tower, scrubbers and fans in the mechanical acid treatment system, seawater treatment devices, seawater heat exchangers, paper industry equipment, sulfuric acid, nitric acid equipment, acid production Pharmaceutical industry and other chemical equipment, pressure vessels, food equipment, pharmaceutical plants: centrifuges, reactors, etc., plant foods: soy sauce tanks, cooking wine, salt tanks, equipment and dressings, 904L is the matching steel for dilute sulfuric acid strong corrosive medium.
