    • A testing method for the bolt to be used under the conditions of excessive wind force by which bolts made of Cr—Mo steel can be separated into a group of bolts usable in cold areas and a group of bolts unusable in cold areas without conducting Charpy impact test involving complicated operation, specifically, a testing method for determining whether bolts made of heat-treated Cr—Mo steel are usable or unusable in cold areas, wherein the determination is conducted on the basis of both J parameter calculated by formula: J=(Si %+Mn %) (P %+Sn %) 104 (wherein P %, Si %, Mn % and Sn % are contents (mass %) of phosphorus (P), silicon (Si), manganese (Mn) and tin (Sn) respectively as disclosed in the inspection certificate of the Cr—Mo steel) and bolt diameter.
    • 在过度风力条件下使用的螺栓的测试方法,由Cr-Mo钢制成的螺栓可以分成一组可用于寒冷地区的螺栓和一组在寒冷地区不可用的螺栓,而不会发生夏比冲击 涉及复杂操作的试验,具体地说,一种用于确定由热处理的Cr-Mo钢制成的螺栓是否可用于冷区域的试验方法,其中基于由以下公式计算的两个J参数进行确定:J =( Si%,Mn%)(P%+ Sn%)104(P%,Si%,Mn%,Sn%是磷(P),硅(Si),锰(Mn) (Sn)分别如Cr-Mo钢的检验证书)和螺栓直径。
