1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has the requirements for forming
Sufficient plasticity. The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is 30-50% less than that of commonly used austenite, which is beneficial to reduce costs.
2) It has excellent resistance to stress corrosion cracking. Even duplex stainless steel with the lowest alloy content has higher resistance to stress corrosion cracking than austenitic stainless steel, especially in environments containing chloride ions. Stress corrosion is an outstanding problem that is difficult to solve for ordinary austenitic stainless steel.
3) The corrosion resistance of 2205 duplex stainless steel, which is the most commonly used in many media, is better than that of ordinary 316L austenitic stainless steel, while super duplex stainless steel has extremely high corrosion resistance, and in some media, such as acetic acid, formic acid etc. can even replace high-alloy austenitic stainless steel and even corrosion-resistant alloys.
4) It has good local corrosion resistance. Compared with austenitic stainless steel with equivalent alloy content, its wear resistance and fatigue corrosion resistance are better than austenitic stainless steel.
5) The coefficient of linear expansion is lower than that of austenitic stainless steel, which is close to that of carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plates or linings.
6) No matter under the condition of dynamic load or static load, it has higher energy absorption capacity than austenitic stainless steel, which has obvious advantages and practical application value for structural parts to deal with sudden accidents such as collision and explosion.
