</p> <p> <br /> </p> <p> 碳鋼。我們以碳鋼料中碳的含量區(qū)分低碳鋼，中碳鋼和高碳鋼以及合金鋼。 </p> <p> <br /> </p> <p> 1、低碳鋼C%≤0.25% 國(guó)內(nèi)通常稱為A3 鋼。國(guó)外基本稱為1008，1015，1018，1022 等。主要用于4.8 級(jí)螺栓及4 級(jí)螺母、小螺絲等無硬度要求的產(chǎn)品。（注：鉆尾釘主要用1022 材料。） </p> <p> <br /> </p> <p> 2、中碳鋼0.25%<C%≤0.45% 國(guó)內(nèi)通常稱為35 號(hào)、45 號(hào)鋼，國(guó)外基本稱為1035，CH38F，1039，40ACR 等。主要用于8 級(jí)螺母、8.8 級(jí)螺栓及8.8 級(jí)內(nèi)六角產(chǎn)品。 </p> <p> <br /> </p> <p> 3、高碳鋼C%>0.45%。目前市場(chǎng)上基本沒使用 </p> <p> <br /> </p> <p> 4、合金鋼：在普碳鋼中加入合金元素，增加鋼材的一些特殊性能：如35、40 鉻鉬、SCM435， </p> <p> 10B38。芳生螺絲主要使用SCM435 鉻鉬合金鋼，主要成分有C、Si、Mn、P、S、Cr、Mo。 </p> <p> <br /> 莆田螺栓包括什么普通螺栓按照制作精度可分為幾個(gè)等級(jí)？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="莆田螺栓包括什么,螺栓"

螺栓強(qiáng)度等級(jí)標(biāo)號(hào)有兩部分?jǐn)?shù)字組成，分別表示螺栓材料的公稱抗拉強(qiáng)度值和屈強(qiáng)比值。例如，性能等級(jí)4.6級(jí)的螺栓，其含義是： </p> <p> 1、螺栓材質(zhì)公稱抗拉強(qiáng)度達(dá)400MPa級(jí)； </p> <p> 2、螺栓材質(zhì)的屈強(qiáng)比值為0.6； </p> <p> 3、螺栓材質(zhì)的公稱屈服強(qiáng)度達(dá)400×0.6=240MPa級(jí)性能等級(jí)10.9級(jí)**度螺栓，其材料經(jīng)過熱處理后，能達(dá)到： </p> <p> 1、螺栓材質(zhì)公稱抗拉強(qiáng)度達(dá)1000MPa級(jí)； </p> <p> 2、螺栓材質(zhì)的屈強(qiáng)比值為0.9； </p> <p> 3、螺栓材質(zhì)的公稱屈服強(qiáng)度達(dá)1000×0.9=900MPa級(jí) </p> <p> 螺栓強(qiáng)度等級(jí)的含義是國(guó)際通用的標(biāo)準(zhǔn)，相同性能等級(jí)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(jì)上只選用性能等級(jí)即可。 </p> <p> <br /> </p><p> 地腳螺栓的安裝規(guī)劃地腳螺栓在基礎(chǔ)內(nèi)松動(dòng)的處理在近擰緊地腳螺栓時(shí)，可能將螺栓拔活，此時(shí)應(yīng)先螺栓調(diào)整至原位置，并將螺栓周圍的基礎(chǔ)鏟出足夠的位置，然后在螺栓上焊縱橫兩個(gè)U形鋼筋，之后用水將坑內(nèi)清洗干凈并灌漿。 </p> <p> <br /> </p> <p> 待混凝土凝固到設(shè)計(jì)強(qiáng)度后再擰緊活地腳螺栓偏差的處理活地腳螺栓偏差的處理方法，大致與死地腳螺栓的方法相同，只是可以將地腳螺栓**處理。如螺栓過長(zhǎng)，可在機(jī)床上切去一段再套螺紋；如螺栓過短，可用熱鍛法伸長(zhǎng)；如位置不符，用彎曲法矯正。 </p> <p> <br /> </p> <p>
