UNS+S32615+ represents what material is the national standard.

Hello, I'm glad to answer your <>

Answer: UNS+S32615+ represents the national standard of Shanzhen, which belongs to the national standard duplex steel, which is the American standard duplex super stainless steel. UNS S32760 is the grade of American Standard Duplex Steel, and the implementation standard:

ASTM A 959-2004 (Guidelines for Uniform Standard Grade Composition of Wrought Stainless Steels). UNS S32760 is a super duplex stainless steel. Contains tungsten and copper, 25% chromium (austenitic ferrite) steel.

**The alloy has a pren (pitting equivalent) number of >, which ensures high pitting resistance. Primarily used in oil & gas and marine applications, it is commonly used in pressure vessels, choke valves, Christmas trees, flanges, and pipeline vibrato systems.

UNS S31803 is a medium-alloy duplex stainless steel with a PREN value of 32-33, and its corrosion resistance is between AISI 316L and 6% Mo+N austenitic stainless steel.

Duplex steel is composed of martensitic, austenitic or bainite and ferrite matrix two-phase structure, obtained by low carbon steel or low-alloy high-strength steel after heat treatment or controlled rolling in the critical zone, the typical yield strength of duplex steel is 310MPa, and the tensile strength B is 655MPa. Duplex steel is used to manufacture complex components of cold drawing and deep drawing, and can also be used as pipeline steel, chains, cold-drawn steel wires, prestressed steel bars, etc.

S31803 belongs to duplex stainless steel. 22% chromium duplex (austenitic ferritic) steel (type 2205) with medium to high strength and good resistance to common corrosion stress, corrosion cracking.

<> alloy is resistant to chloride environments and sulfide stress corrosion, and is approximately twice as strong as standard austenitic stainless steels. Higher mechanical strength is required At a lower weight, the alloy can be successfully used as a replacement for 300 series austenitic stainless steels. The F51 is easy to weld with many standard arc welding equipment, but is not recommended for oxyethylene welding because of the carburization of the welded metal that may occur with Sharp Silver.

S31803 is developed on the basis of SAF2205 in Sweden, which is the most common steel grade used in the world's two-way steel, which is resistant to the environment containing curing hydrogen, carbon dioxide and chlorine contact chemicals, and can be formed by cold and hot processing, with good welding performance, and is suitable for structural materials instead of 304 and 316.
