1、螺栓材質(zhì)公稱抗拉強(qiáng)度達(dá)400MPa級； 2、螺栓材質(zhì)的屈強(qiáng)比值為0.6； 3、螺栓材質(zhì)的公稱屈服強(qiáng)度達(dá)400×0.6=240MPa級性能等級10.9級**度螺栓，其材料經(jīng)過熱處理后，能達(dá)到： 1、螺栓材質(zhì)公稱抗拉強(qiáng)度達(dá)1000MPa級； 2、螺栓材質(zhì)的屈強(qiáng)比值為0.9； 3、螺栓材質(zhì)的公稱屈服強(qiáng)度達(dá)1000×0.9=900MPa級螺栓性能等級的含義是國際通用的標(biāo)準(zhǔn)，相同性能等級的螺栓，不管其材料和產(chǎn)地的區(qū)別，其性能是相同的，設(shè)計上只選用性能等級即可。強(qiáng)度等級所謂8.8級和10.9級是指螺栓的抗剪切應(yīng)力等級為8.8GPa和10.9GPa 10.9s的s

螺栓檢測方式有： </p> <p> <br /> </p> <p> 螺栓檢測分為人工和機(jī)器兩種。人工是原始也是使用為普遍的一致檢測方式。為了盡量減少不良品的流出，一般生產(chǎn)企業(yè)人員通過目視的方式對待包裝或者發(fā)貨的產(chǎn)品進(jìn)行檢驗，以排除不良品（不良包括牙傷、混料、生銹等）。 </p> <p> <br /> </p> <p> 另一種方式為機(jī)器全自動檢測，主要是磁粉探傷。磁粉探傷是利用螺栓缺陷處的漏磁場與磁粉的相互作用，針對螺栓可能存在的缺陷（如裂紋，夾渣，混料等）磁導(dǎo)率和鋼鐵磁導(dǎo)率的差異，磁化后這些材料不連續(xù)處的磁場將發(fā)生崎變。 </p> <p> <br /> </p> <p> 形成部分磁通泄漏處工件表面產(chǎn)生了漏磁場，從而吸引磁粉形成缺陷處的磁粉堆積——磁痕，在適當(dāng)?shù)墓庹諚l件下，顯現(xiàn)出缺陷位置和形狀，對這些磁粉的堆積加以觀察和解釋，已達(dá)到剔除不良品的目的。 </p> <p> <br /> 螺栓大概有幾種分類？南通五金螺栓</p><p style="text-indent:25px">螺栓的符號表示有哪些？南通五金螺栓</p><p> **度螺栓摩擦型和承壓型連接的區(qū)別： </p> <p> **螺栓連接是通過螺栓桿內(nèi)很大的擰緊預(yù)拉力把連接板的板件夾緊，足以產(chǎn)生很大的摩擦力，從而提高連接的整體性和剛度，當(dāng)受剪力時，按照設(shè)計和受力要求的不同，可分為**螺栓摩擦型連接和**螺栓承壓型連接兩種，兩者的本質(zhì)區(qū)別是極限狀態(tài)不同，雖然是同一種螺栓，但是在計算方法、要求、適用范圍等方面都有很大的不同。在抗剪設(shè)計時，**螺栓摩擦型連接是以外剪力達(dá)到板件接觸面間由螺栓擰緊力所提供的可能大摩擦力作為極限狀態(tài)，也即是保證連接在整個使用期間內(nèi)外剪力不超過大摩擦力。板件不會發(fā)生相對滑移變形（螺桿和孔壁之間始終保持原有的空隙量），被連接板件按彈性整體受力。在抗剪設(shè)計時，**螺栓承壓型連接中允許外剪力超過大摩擦力，這時被連接板件之間發(fā)生相對滑移變形，直到螺栓桿與孔壁接觸，此后連接就靠螺栓桿身剪切和孔壁承壓以及板件接觸面間的摩擦力共同傳力，以桿身剪切或孔壁承壓破壞作為連接受剪的極限狀態(tài)。南通五金螺栓</p><p
