The Influence of Cooling Rate from High Temperature upon the Cavitation Erosion Resistance of the Duplex Stainless Steel X2CrNiMoN22-5-3

Abstract:

Duplex stainless steels are processed by a process of hot or cold plastic deformation and welding operations. Their properties of the use depend on the type of product (deformed, welded) and to the final heat treatment. The proportion of the basic structural constituents (austenite and ferrite) essentially depends on the chemical composition and cooling rate from high temperatures. This paper shows the that slow cooling in the furnace at the high temperature (1060 ° C) lead to a predominantly austenitic microstructure (cca.75%) while that cooling in the water sudden limited the transformation austenite → ferrite, so that the microstructure will be composed of cca.52% F + 48% A.These modifications by structure justify the changes the occurring with respec ultrasonic erosion cavitation behavior.
