UNS S32950 Super Duplex Stainless Steel Chemical Composition Properties, Grade, Table and Document

UNS S32950, a super duplex stainless steel, displays remarkable corrosion resistance, but it is also recognized for its mechanical properties. Sometimes the chemical composition of the steel, which is usually a mixture of such as chromium, nickel, molybdenum, and nitrogen is a great plus due to the ability to provide excellent performance in extreme conditions. The alloy boasts a unique microstructure which is made of grains in two phases. This particular structure allows for great mechanical strength as well as corrosion resistance. This is why it is primarily used for chemicals, oil and gas, and marine applications. Grade S32950 respects international standards and specifications therefore ensuring the recurrence and reliability of successful performance. The chemical composition, properties and standards applicable to this material are detailed in table, chart and document form which can be used as references in making informed material selection and engineering decisions in tight applications.

UNS S32950 Super Duplex Stainless Steel Chemical Composition And Grade Table

UNS S32950 is a grade of super duplex stainless steel recognized by its extremely high corrosion resistance alongside the best mechanical properties printed offer. Its chemical composition usually contains chromium, nickel, molybdenum and nitrogen which make the alloy very strong and resistant to pitting, crevice corrosion and stress corrosion cracking. The chemical composition of this alloy may vary slightly depending on the specific manufacturer specifications, but usually it contains about 25% chromium, 7% nickel, 4% molybdenum, and 0.3% nitrogen. These properties make UNS S32950 a good option for the applications in different sorts of environments where corrosion-resistance is a big concern.
