The difference between duplex 2205 stainless steel tube and ferritic 410 stainless steel tube

Posted by:Rain Time:2019.11.26 18:00

1) The comprehensive mechanical properties are better than ferritic stainless steel, especially plastic toughness, not as sensitive to brittleness as ferritic stainless steel.

 

2) In addition to stress corrosion resistance, other local corrosion resistance is superior to ferritic stainless steel.

 

3) Cold working process performance and cold forming performance are much better than ferritic stainless steel.

 

4) The welding performance is also much better than that of ferritic stainless steel. Generally, no preheating is required before welding, and no heat treatment is required after welding.

 

5) The application range is wider than that of ferritic stainless steel.

 

Compared with ferritic stainless steel, the disadvantages of duplex stainless steel are as follows: high alloying elements and relatively high price, generally ferrite does not contain nickel.
