Product Details

Our duplex stainless steel UNS S32205 tubes are truly enduring. The range of these duplex S32205 tubes allows them to be matched for corrosion resistance with the austenitic and ferritic steel grades. Meanwhile, when these duplex steel S32205 pipes are melted it solidifies from the liquid phase to a completely ferritic structure. ASTM A789 duplex steel S32205 tubing is two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. ASEM SA789 duplex steel S32205 seamless pipe 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.
