Product Description

Duplex Steel 2205 Seamless Tube is a nitrogen improved duplex stainless steel that was created to battle regular consumption issues experienced with the 300 arrangement stainless steels. "Duplex" depicts a group of stainless steels that are neither completely austenitic, similar to 304 stainless, nor simply ferritic, similar to 430 stainless. The structure of 2205 duplex stainless steel comprises of austenite pools encompassed by a nonstop ferrite stage. In the toughened condition, 2205 contains roughly 40-50% ferrite. Frequently alluded to as the work stallion review, 2205 is the most generally utilized review as a part of the duplex group of stainless steels.

The upside of a duplex structure is that it joins the positive characteristics of a ferritic amalgam (stress erosion breaking resistance and high quality) with those of an austenitic combination (simplicity of creation and consumption resistance).

Utilization of 2205 Duplex stainless steel ought to be constrained to temperatures beneath 600° F. Amplified hoisted temperature introduction can embrittle 2205 stainless.
