2205 duplex stainless steel plate


1) 2205 duplex stainless steel plate yield strength than ordinary austenitic stainless steel more than doubled, and the need for molding enough plastic toughness. The use of duplex stainless steel manufacturing tank or pressure vessel wall thickness than the commonly used austenite to reduce 30-50%, is conducive to reducing costs;

2) has excellent resistance to stress corrosion cracking, even with the lowest amount of alloying duplex stainless steel also has a higher resistance to corrosion than austenitic stainless steel, especially in chloride ion environment. Stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve;

3) The most common 2205 duplex stainless steel plate is used in many media. Corrosion resistance is better than ordinary 316L austenitic stainless steel, while super duplex stainless steel has high corrosion resistance, and in some media such as acetic acid, And so can even replace the high alloy austenitic stainless steel, and even corrosion resistant alloy.

4) has good resistance to local corrosion, compared with the alloy content of austenitic stainless steel, its wear resistance corrosion and fatigue corrosion performance is better than austenitic stainless steel;


5) than the austenitic stainless steel linear expansion coefficient, and carbon steel close to, suitable for connection with carbon steel, has important engineering significance, such as the production of composite panels or lining;

6) Both the dynamic load and static load conditions, the austenitic stainless steel has a higher energy absorption capacity, which structural parts to deal with emergencies such as collision, explosion, etc., duplex stainless steel has obvious advantages, practical value.
