00Cr24Ni6Mo2N duplex stainless steel has superior corrosion resistance. After normal heat treatment its structure is consist of 50% ferrite and 50% austenite. The pitting corrosion is formed difficultly because its high pitting breakdown potential (Eb is + 1050mv) and protective potential (Ep is + 950mv). It would be passivated again even if there is pitting corrosion hole, which is also proved by both the room accelerated corrosion test and the marine corrosion test . The properties of the stress corrosion resistance and the impingement corrosion resistance are excellent too. It is believed that the 00Cr24Ni6Mo2N duplex stainless steel will be widely used and have a nice prospect.
