ASTM A789 Duplex Stainless Steel S31803/2205 Seamless Tubing 19.05x1.2mm

 

 

Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205, and was endorsed in the year 1996. This grade offers higher resistance to corrosion.

At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.

 

 

The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance).

Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. Extended elevated temperature exposure can embrittle 2205 stainless.

 

2205 Stainless Steel is far superior to standard marine grade 316 and 316L.

 

2205 Stainless Steel has been developed over the last 10-20 years by metallurgists that required a stainless that was not only stronger than standard marine grade 316, but offered much better corrosion resistance. (2205 is commonly used for marine propeller shafts.)

2205 Stainless achieves almost twice the corrosion resistance to ordinary 316. This is due to added levels of Nickel, Chromium, Molybdenum and Nitrogen.
