在不銹鋼螺栓的使用中A4-80外六角螺栓的優(yōu)勢(shì)。外六角的制造成本要比內(nèi)六角低的多了,它的優(yōu)勢(shì)還有螺頭(扳手受力位置)比內(nèi)六角薄,有的地方不是內(nèi)六角可以取代的。另外成本低,動(dòng)力強(qiáng)度小,精度要求低的機(jī)械采用的內(nèi)六角螺釘要比外六角少的多。一般外六角螺釘上都是制成部分螺紋,全螺紋外六角螺釘主要用于公稱長(zhǎng)度羅短的外六角經(jīng)及要求較長(zhǎng)螺紋的場(chǎng)合，江蘇質(zhì)量A4-80 DIN931多重優(yōu)惠。帶孔外六角螺釘用于需要外六角螺釘鎖定的場(chǎng)合。帶鉸制孔用外六角螺釘能精確的固定被連接零件的相到位置。并能受由模向力產(chǎn)生的剪切和擠壓。外六角的優(yōu)點(diǎn)就是預(yù)緊接觸面積大,可以用很大的預(yù)緊力，江蘇質(zhì)量A4-80 DIN931多重優(yōu)惠,一般用在大設(shè)備上，江蘇質(zhì)量A4-80 DIN931多重優(yōu)惠,價(jià)格比內(nèi)六角低,。 </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇質(zhì)量A4-80

style="text-indent:25px">A4L-80和A4-80緊固件的加工難點(diǎn)在于其性能要達(dá)到80的強(qiáng)度。80指的是抗拉強(qiáng)度相當(dāng)小800N/mm2.是屬于不銹鋼中的**度螺栓。碳鋼**度螺栓可以通過(guò)熱處理來(lái)達(dá)到，而不銹鋼不能做熱處理。只能通過(guò)冷作硬化來(lái)達(dá)到其性能。A4L-80主要使用在對(duì)防腐要求和強(qiáng)度要求比較高的地方。如紙漿和造紙用設(shè)備熱交換器、染色設(shè)備、膠片沖洗設(shè)備、管道、沿海區(qū)域建筑物外部用材料，船舶海工，大型戶外游樂(lè)設(shè)備，風(fēng)力發(fā)電設(shè)備，鋼結(jié)構(gòu)，石油化工行業(yè)，汽輪機(jī)等。BEIERSDORF上海在A2-80、A2-90、A2-100、A4-80、A4L-80、A4-90、A4-100、A5-80、C3-80、 C1-110、2205、1.4462、S31803、F51、F53、F55、904L、1.4462、630、660、17-4PH、17-7PH、 C276、A286、B7、B7M、B8、B8M、B16、L7、L7M等性能和材料的方面，具有強(qiáng)大的研發(fā)能力和齊全的安全庫(kù)存，是您質(zhì)量的緊固件合作伙伴。 </p><div

style="text-indent:25px">A4-80內(nèi)六角螺栓的優(yōu)勢(shì)：內(nèi)六角螺釘常用于機(jī)械上,主要有便于緊固,拆卸,不容易滑角等優(yōu)勢(shì)。內(nèi)六角扳手一般都是一個(gè)90°拐彎的。一端長(zhǎng)一邊短,用短的一邊打螺釘時(shí),手握長(zhǎng)的一邊可以省很多的力并且能更好的緊固螺釘。長(zhǎng)的一端有分圓頭(六角圓柱類似球體)和平頭,圓頭可以很方便的斜入拆卸,安裝某些不方便下扳手的部位。內(nèi)六角的優(yōu)點(diǎn)就是占空間小,可以做沉頭,一般用在小設(shè)備上,缺點(diǎn)是預(yù)緊接觸面積小不能用太大的預(yù)緊力,價(jià)格貴一點(diǎn),超過(guò)一定長(zhǎng)度就沒(méi)有全螺紋。</p><div
