Study of RV52 Steel Plates Properties after Thermic Treatment

Abstract

The thermal treatment of RV52 steel plates determines high mechanical properties such as: strength, wear resistance and tenacity. The normalized plate samples were studied to determine the effect of the tension release heat treatment on the properties of steel plates used for metallic welded construction. From the relations expressing the link between the strength and tenacity relation on one hand and the structural characteristics, on the other it is obvious that the only factor which leads both to increasing strength properties and decreasing transition temperature is the finishing of the ferrite grains.
