2205 Stainless Steel Strips Astm Aisi 2205 Stainless Steel Strip
2205 Stainless Steel Strip Features:
Early dual phase stainless steel can resist uniform corrosion of medium strength and chlorine stress corrosion fracture, but its performance will be greatly reduced when it is used in welding. In order to improve this situation, nitrogen is added to the duplex stainless steel 2205, which not only improves the corrosion resistance, but also has a good welding performance. Due to the special performance characteristics of 2205 dual phase steel, it has a wide range of applications and has been widely used.

Difference Between Grade 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 duplex structure of 2507 gives it strong resistance to stress corrosion cracking.
Due to its higher alloy content, the corrosion resistance and strength of 2507 stainless steel strips are better than 2205 stainless steel strips.
2507 stainless steel is especially suitable for offshore oil and gas mining equipment.
