This research is aimed to analyze the microstructure and hardness properties of SAE 52100 steel straightening strokes based on experimental and theoretical investigation with different cross sectional shapes based on different heat treatment conditions. The heat treated samples are used for the design and manufacturing of straightening process. Through various experiments and simulations for the guide rail, we got the relationship between the loading stroke with different heat treatment and the loading stroke with cross section shape, and also the result of hardness testing curves and straightening stroke were discussed briefly. The quality and precision of straightness steel bar mainly depends on the results of hardness of heat treatment and microstructure of metal bar. Results put forward to the best method of selecting heat treatment methods and providing the theoretical basis for improving straightening precision and developing the optimal straightening process.
