45號鋼、40硼鋼、20錳鈦硼鋼。普通螺栓常用Q235鋼制造。 </p> <p> <br /> </p> <p> 2.從強(qiáng)度等級上看，**螺栓，使用日益普遍。常用8.8s和10.9s兩個(gè)強(qiáng)度等級，其中10.9級居多。普通螺栓強(qiáng)度等級要低，一般為4.4級、4.8級、5.6級和8.8級。 </p> <p> <br /> </p> <p> 3.從受力特點(diǎn)來看，普通螺栓連接靠栓桿抗剪和孔壁承壓來傳遞剪力，而**螺栓除了其材料強(qiáng)度很高之外，還給螺栓施加很大預(yù)拉力，使連接構(gòu)件間產(chǎn)生擠壓力，從而使垂直于螺桿方向有很大摩擦力。 </p> <p> <br /> </p><p> 螺栓的表示方法是直徑和長度。普通的粗牙螺紋是這樣標(biāo)注的M8*15.細(xì)牙是M8*15*1.也就是要把回螺距也標(biāo)注上去。答粗牙是不標(biāo)螺距的，細(xì)牙才標(biāo)。 </p> <p> 螺栓：由頭部和螺桿（帶有外螺紋的圓柱體）兩部分組成的一類緊固件，螺栓需與螺母配合，用于緊固連接兩個(gè)帶有通孔的零件。這種連接形式稱螺栓連接。如把螺母從螺栓上旋下，又可以使這兩個(gè)零件分開，所以螺栓連接是屬于可拆卸連接。其中六角頭是常用的，一般沉頭用在要求連接的地方。 </p> <p> <br /> 六角頭螺栓分外六角螺栓和內(nèi)六角螺栓，是常用的緊固件，主要用作機(jī)械設(shè)備的緊固。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="螺栓電話,螺栓"

**螺栓所用材料的比較大抗拉強(qiáng)度與淬火處理有很大關(guān)系，40Cr淬火處理后一般較難達(dá)到10.9S級**螺栓的材質(zhì)要求，在不是很嚴(yán)格的檢驗(yàn)中，可以根據(jù)淬火處理后的表面硬度來判斷材料的比較大抗拉強(qiáng)度。除了處理工藝中的性能不同外，材質(zhì)不同的**螺栓，其在高應(yīng)力狀態(tài)下的延遲性斷裂性能也是有所不同的。 </p> <p> 40Cr**螺栓主要用于螺栓球節(jié)點(diǎn)網(wǎng)架中，其設(shè)計(jì)強(qiáng)度一般為390MPa(d>=30mm)或者430MPa（d<30mm)，使用中不存在很高的預(yù)拉應(yīng)力。當(dāng)用于要施加很高預(yù)拉力的情況時(shí)，要注意了解和保證其延遲性斷裂性能。20MnTiB**螺栓的延遲性斷裂性能好于40B的。螺栓的應(yīng)用在哪些行業(yè)？綏化螺栓銷售廠家</p><p style="text-indent:25px">螺栓的等級和螺栓的材質(zhì)有關(guān)嗎？螺栓電話</p><p> 螺栓的等級和材質(zhì)是沒有關(guān)系的。 </p> <p> <br /> </p> <p> 主要和螺栓的加工精細(xì)程度，如果為A,B級螺栓要求4102螺栓的制造誤差要低，同時(shí)對螺栓孔的允許偏差和粗糙度比C級螺栓也要高。 </p> <p> <br /> </p> <p> 舉一例說明： </p> <p> <br /> </p> <p> 4.8級六角頭螺栓與Q235B六角頭螺栓相比較，4.8級螺栓是要求螺栓材質(zhì)的抗拉強(qiáng)度達(dá)到400MPa，屈服比為0.6，那么屈服強(qiáng)度就是400*0.6=240MPa。 </p> <p> <br /> </p> <p> 對比Q235的螺栓，要求螺栓材質(zhì)的屈服強(qiáng)度大于235MPa，與4.8級螺栓是差不多的。 </p> <p> <br /> </p> <p> 因此選擇螺栓的性能等級與選擇材質(zhì)沒有太大的差別，選擇任何一種表示方法作為螺栓的技術(shù)要求都是可以的。 </p> <p> <br /> 螺栓電話</p><p
