其中,SAE J429分为Gr.2、Gr.5、Gr.8等三个等级,而ASTM A354则分为Gr.BC和Gr.BD两个等级。不同等级的螺栓在标识方式上也有所不同。例如,SAE J429等级的螺栓通常通过带有“Grade”或“G”的标记进行区分,如Grade 2、Grade 5等;而ASTM A354等级的螺栓则一般通过将等级标识写在螺栓名称前面的方式进行区分...
A354 Grades BD Grade BD bolts are higher in strength than grade BC, and equal in strength to ASTM F3125 grade A490 bolts. Unlike A490 however, the A354 standard is unrestricted in its configuration. Also, since A490 bolts are for structural use and do not exceed 1-1/2” in diameter,...
