针对糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版的布氏糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版取值问题，对部分同种材料锻件的布氏糖心产精国品免费入口*完整版与抗拉强度数据进行了统计分析，并给出了布氏糖心产精国品免费入口*完整版与抗拉强度换算的关系公式；对600 MW超临界机组安装现场F91（即10Cr9Mo1VNbN）钢大直径锻制三通成品进行了表面糖心产精国品免费入口*完整版测试以验证其糖心产精国品免费入口*完整版均匀性。在参照国内外相关标准对同类材料糖心产精国品免费入口*完整版规定的基础上，研究分析确定：糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版的布氏糖心产精国品免费入口*完整版应控制在190～248 HBW，同一锻件的糖心产精国品免费入口*完整版均匀性偏差应不大于40 HBW。

To determine the standard Brinell 糖心产精国品免费入口*完整版 values of 10Cr9Mo1VNbN steel 糖心产精国品免费入口*完整版s, the statistic analysis on the Brinell 糖心产精国品免费入口*完整版 and tensile strength of a number of the same material forgings was performed and the formula of the relationship between these two characteristic parameters was given. The surface 糖心产精国品免费入口*完整版 test was done for the F91 (namely 10Cr9Mo1VNbN) steel large diameter forged tees used in 600 MW super-critical units at erection site to verify the 糖心产精国品免费入口*完整版 evenness. On the basis of the statistic analysis, testing results and requirements of the domestic and foreign standards for similar or same materials, it was determined that the standard Brinell 糖心产精国品免费入口*完整版 values of 10Cr9Mo1VNbN steel 糖心产精国品免费入口*完整版s should be controlled in 190-248 HBW and the 糖心产精国品免费入口*完整版 difference of one piece should be limited to no more than 40 HBW.
