1. Heat Treatment Process of Cast Steel Joint Steel casting parts have a lot of detailed issues,today,let’ s talk about heat treatment process of cast steel joint. The heat treatment process of cast steel joint have 3 steps: heating, heat preservation and cold.Heat treatment methods including annealing,normalizing,normalizing and tempering.Three methods lead to different mechanical property,for the simple structure,thickness is not too thick,tempering is normal method.For complex structure,easy deformation and crack,annealing is suitable. Normalizing and tempering is used to thick carbon steel casting parts and low alloy steel casting parts. The purpose of tempering is to remove stress of casting joint, avoid deformation and crack.The

2. temperature and time of heat treatment is the key,temperature and time table are the important documents to monitor heat treatment reasonability.
