UNS S32205 - Grade 2205 Duplex Stainless Steel
Introduction
Overview of UNS S32205 Duplex 2205 Stainless Steel
UNS S32205 duplex stainless steel, also known as 2205 duplex stainless steel, is a nitrogen-enhanced stainless steel.
Customers choose duplex UNS S32205 materials for its excellent corrosion resistance along with its high strength.
It is important to note that UNS S32205 duplex, offers much higher levels of corrosion resistance than most other austenitic stainless steels.
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 grade 2205 stainless steel is not suitable for use at these temperatures.

Why 2205 Stainless Steel Strip Is Used In Finned Tube?
2205 stainless steel strip is one of the major duplex strip materials for finned tube production. If you are the beginner of this area, you can benefit from this guide. By the end of this blog, you will have full understanding on all aspects of duplex 2205 stainless steel strip for finned tubes.
What’s The Difference Between 2205 And 2507 Stainless Steel Strip?
2205 and 2507 stainless steel strips are stainless steels containing molybdenum. The molybdenum content in 2507 stainless steel strip is slightly higher than 2205 stainless steel strip. Due to the molybdenum and high chromium contents in the stainless steel, the overall performance of 2205 and 2507 stainless steel strip is better than 317L stainless steel strip.
The History Of Duplex 2205 And 2507 Stainless Steel
Duplex 2205 and 2507 stainless steel is an alloy which combines many of the most beneficial properties of ferritic steel and austenitic steel. Due to the high content of chromium and molybdenum, the steel has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion.
