Abstract

Abstract: Solution treatment and incomplete annealing were carried out for 8Cr13 martensitic stainless steel, then the carbides refinement and its effect on the final properties of the steel after quenching and tempering was studied. The results show that high temperature solution treatment and incomplete annealing process can effectively refine the carbides in the 8Cr13 steel. With the increase of solution treatment temperature and the extension of solution time, the carbides gradually dissolve, and the volume fractions and sizes of carbides decrease. Compared with the specimen directly quenched and tempered without solution treatment, the specimen solution treated at 1100 ℃ for 4 h and incomplete annealed can obtain the best comprehensive properties after quenching and tempering. The yield strength, tensile strength and elongation are increased by 30.6%, 8.3% and 147.7%, respectively, the hardness is slightly reduced but meets the requirements, and the self-corrosion current density is reduced by one order of magnitude.
