高強度螺栓

螺栓性能等級的含義是什么?

數字:

       螺栓上的數字是指強度等級,比如說數字4.8是說螺栓的強度等級為4.8級,其抗剪切應力為4.8GPa。按照規定,強度等級為8.8級以上的螺栓統稱為高強度螺栓,其余統稱為普通螺栓。        一般的螺栓是用"X.Y"表示強度的,X*100=此螺栓的抗拉強度,X*100*(Y/10)=此螺栓的屈服強度(因為按標識規定:屈服強度/抗拉強度=Y/10)。如4.8級?? 則此螺栓的抗拉強度為:400MPa;屈服強度為:400*8/10=320MPa。

       字母:

       螺栓上的字母是沒有什么標準統一的含義的,字母是每個廠家在生產時打的廠家標記,比如說 柴氏汽摩配件有限公司 制造的螺栓就會打上"TC",表示天聰制造。
