Product Introduction

2205 Duplex Stainless Steel Tubing high chromium, molybdenum, and nitrogen makes it more corrosion resistant than common stainless steels, such as 316L and 317L, in most environments. In the annealed condition, alloy 2205 is more than twice as strong as conventional austenitic stainless steels. It is also available in the cold worked condition with a yield strength of over 160 ksi. It maintains good toughness at temperatures as low as -50°F (-10°C). The ASME Boiler and Pressure Vessel Code specifies an upper temperature limit of 600°F (315°C).
