ASTM A240 UNS S31803 2205 duplex Stainless Steel Coil

Prosaic Steel and Alloys is committed to provide  each and  every customer  with the highest  standard of  customer  service.


Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.
