General Duplex Stainless Steel Information
Duplex Stainless Steel 2205 is the most widely used duplex stainless steel grade. Also Known as: UNS: UNS S31803 – UNS S32205; SAF: SAF 2205® 22Cr; ASME SA-182 (F51), SA-182 (F60), SA-240, SA-798, SA-790, SA-815; ASTM A182 (F51), A182 (F60), A240, A276, A479, A480, A789, A790, A815, A928, A988; SAE J405
Duplex Stainless Steel 2205 is also called as Duplex 2205. The term of “Duplex” means that the steel consists of a two-phase microstructure — both ferritic stainless steel and austenitic stainless steel. Nitrogen is enhanced in Duplex 2205 comparing to other duplex stainless steel.
The Advantage of Duplex Stainless Steel Casting:
It combines the benefits of ferritic alloy (which provides high strength & stress corrosion cracking resistance) and austenitic alloy (which provides corrosion resistance & easy on fabrication.
Corrosion Resistance:
Duplex Stainless Steel 2205 is very cost-effective for various applications that require corrosion resistance. The combination of chromium, molybdenum and nitrogen provides good resistance to crevice corrosion and chloride pitting. Corrosion resistance is highly important for applications in marine environments, bleaching operations, and food processing etc.
