%X The cavitation erosion behavior of Cr-Mn-N austenite-ferrite stainless steel was investigated by ultrasonic vibration cavitation erosion equipment. The results show that the resistance of Cr-Mn-N stainless steel to cavitation erosion is superior to that of OCrl3Ni5Mo stainless steel although Cr-Mn-N stainless steel has lower hardness. The ferrite phase in the surface of Cr-Mn-N steel is quickly removed when it is damaged by cavitation erosion, and its volume content in the surface of Cr-Mn-N steel quickly decreased from 19% to 6.9%, then keeps invariable. The austenite is prone to remove from the pits left by ferrite removal. Work hardening is an important way for Cr-Mn-N stainless steel to absorb cavitation erosion impact energy, which makes Cr-Mn-N stainless steel exhibit superior resistance to cavitation erosion.
