Introduction of 2205 stainless steel:
Yield strength of 2205 duplex stainless steel is two times of that of the austenitic stainless steel, this feature enables designers to reduce weight in the design of products, let this alloy has a price advantage than 316317L. This alloy is particularly applicable to -50 degrees F/+600 degrees F temperature range. Beyond this temperature range of applications, also can consider this kind of alloy, but there are some limitations, especially when used in welding structure.

The characteristics of 2205 stainless steel:
Compared with the ferritic stainless steel and martensitic stainless steel, duplex stainless steel with high toughness, low brittle transition temperature, resistance to intergranular corrosion resistance and welding performance were significantly increased, while retaining the ferrite stainless steel and high rate of thermal conductivity, small coefficient of linear expansion, has some characteristics such as superplasticity; compared with Austenitic stainless steel, its strength is higher, especially yield strength significantly increased, and the resistance to intergranular corrosion, should have significantly improved the stress corrosion and corrosion fatigue properties
