329 stainless steel introduction
SUS329 is a duplex stainless steel with a high proportion of chromium, nickel and molybdenum in its chemical composition. The main standard is JIS G4304. The chemical composition of SUS329 steel contains 25-28% chromium and 3-6% nickel. , the molybdenum content is 1-2%, etc. This proportion of chemical composition gives SUS329 steel excellent corrosion resistance, wear resistance and strength. Specifically, SUS329 steel has the following performance characteristics: High strength and good toughness: SUS329 steel has high yield strength and tensile strength, as well as good plasticity and toughness. Good corrosion resistance: The high chromium, high molybdenum and other components of SUS329 steel give it good corrosion resistance, including good corrosion resistance to corrosive media such as sulfuric acid, hydrochloric acid, chloride and seawater. Advantages of Duplex Stainless Steel SUS329 is a duplex stainless steel that has both the advantages of austenite and the advantages of ferrite. It has higher strength and better corrosion resistance than ordinary austenitic stainless steel. Easy to process and form Because of its good plasticity and toughness, SUS329 steel is easy to process and form, and can adapt to a variety of forming processes. Based on the above characteristics, SUS329 steel is widely used in marine engineering, chemical industry, petrochemical industry, papermaking, medicine and food processing and other fields. It is used to manufacture equipment and parts such as corrosion-resistant vessels, pipes, valves and pumps. It should be noted that when using SUS329 steel, factors such as heat treatment temperature, cooling rate, and welding parameters need to be controlled to maintain the excellent performance of the material and ensure safe use.
