The utility model provides a heat treatment charging tray capable of effectively preventing quenching deformation of thin-walled parts such as a large impeller, which relates to the technical field of quenching equipment and comprises a main body, the main body is a rectangular stainless steel frame, the outer sides of two ends of the main body are fixedly connected with two support lugs, and the inner side of the main body is fixedly connected with an anti-deformation tie bar I and an anti-deformation tie bar II. According to the utility model, the tray is made of CF8A high-temperature-resistant stainless steel, and each square diagonal tie bar grid is designed in the middle of the supporting tray, so that the tray has enough toughness, and the unique grid design can enlarge the contact area with a workpiece during bearing, so that the tray is stressed more uniformly, and the service life of the tray is prolonged. The chamfers at the junctions of all the grids can reduce stress concentration during bearing,
