In the inspection of power plant boiler, the 糖心产精国品免费入口*完整版 detected on site is usually converted into 糖心产精国品免费入口*完整版. However, the existing 糖心产精国品免费入口*完整版does not make a detailed distinction between different materials, and the range of hardness is not wide enough. The end-quenching and integral 糖心产精国品免费入口*完整版 experiments of P22 steel were carried out. The hardness values of Leeb and Brinell with wider hardness range and more uniform distribution were obtained, and then the 糖心产精国品免费入口*完整版between 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版 was established. The results show that there was a quadratic regression relationship between the 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版, and the 糖心产精国品免费入口*完整版is
HBW=0. 001 6HLD2-0. 66HLD+155. 7.
