Since these grades include both austenitic and ferritic phases, they are referred to as "duplex" or "austenitic-ferritic." They're tougher and more corrosion-resistant than typical austenitic stainless steels like Type 304 and Type 316, and they're optimized to withstand the effects of chloride stress corrosion

UNS S32205 contains higher nitrogen content which gives it extra strength. Hence, it is super safe. It provides an additional protective cover against any corrosive compounds. UNS S32205’s heightened corrosion resistance gives it a significant distinction from UNS S31803.

Duplex stainless steels are a family of alloys characterized by a two-phase microstructure consisting of both ferritic and austenitic phases. The 2205 variant, also known as UNS S32205 or EN 1.4462, comprises approximately 22% chromium, 5-6% nickel, 3% molybdenum, and a balanced amount of other essential elements such as nitrogen, manganese, and iron.

Stainless steel welded pipes are made by welding a rolled sheet of stainless steel into a tube using a welding process. The welding can be done using various methods, such as TIG, MIG, or electric resistance welding. The welded joint is then annealed to restore the material's corrosion resistance and strength.

Duplex stainless steel is a very useful metal that is used the world over. It gets its name from the fact that it consists of two different grades of metal.

Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion, and stress corrosion cracking. Moreover, they have improved toughness and ductility compared to ferritic SS.

Stainless steel is renowned for its corrosion resistance and durability, making it an ideal choice for various applications. Among the numerous stainless steel grades available, two of the most popular and widely used are 304 and 316. These two alloys share many similarities but also exhibit distinct differences, particularly when it comes to stainless steel fittings.

Stainless steel pipe fittings are integral components in various industries, serving the critical role of connecting and diverting fluids in pipelines. These fittings come in a wide array of types, each designed for specific applications and requirements.
