偽劣鋼材材質(zhì)含雜質(zhì)多，鋼的密度偏小，而且尺寸超差嚴(yán)重，所以在沒(méi)有游標(biāo)卡尺的情況下，可以對(duì)它進(jìn)行稱量核對(duì)。比如對(duì)于螺紋鋼2，標(biāo)準(zhǔn)中規(guī)定負(fù)公差為5％，定尺9M時(shí)它的單根理論重量為12公斤，它的的重量應(yīng)該是：12X（l－5％）＝114公斤，稱量出來(lái)單根的實(shí)際重量比114公斤小，則是偽劣鋼材，原因是它負(fù)公差超過(guò)了5％。一般來(lái)說(shuō)整相稱量效果會(huì)更好，主要考慮到累積誤差和概率論這個(gè)問(wèn)題。、偽劣鋼材的內(nèi)徑尺寸波動(dòng)較大，原因是；l、鋼溫不穩(wěn)定有陰陽(yáng)面。
