從技術(shù)工藝上來說不銹鋼墊圈比65Mn鋼墊圈制造難道略微大一些，從材料價格上來說不銹鋼墊圈比65Mn鋼墊圈成本高一些；關(guān)鍵是要符合客戶的需求。<br /> 從性能上來說不銹鋼墊圈比65Mn鋼墊圈的彈性要差一些。制造難度大一些。<br /> 不銹鋼彈簧墊圈的彈性性能要求是根據(jù)供需雙方協(xié)議確定的，達不到標準中規(guī)定的彈性試驗要求。<br /> 從功能上講：不銹鋼彈性墊圈通常都是奧氏體不銹鋼制造的，由于不涉及熱處理，其彈性主要來自于冷加工的冷作硬化(英文叫STRAIN HARDENED) ，所以彈性比較一般，很多其實達不到標準要求。而65Mn的墊圈通過熱處理，彈性性能比較優(yōu)異并且穩(wěn)定。從制造工藝上講：兩者差不多，不銹鋼由于材料偏硬一些，制造難度稍大，但65Mn由于要熱處理及表面處理，過程更冗長一些。加大墊片廠商內(nèi)齒彈性墊圈、外齒彈性墊圈：圓周上具有很多銳利的彈性翹齒，刺壓在支承面上，能阻止緊固件的松動。</p><div

style="text-indent:25px">彈簧墊圈（DIN127B/GB93）開口脹圈及氫脆斷裂原因：1.彈簧墊圈發(fā)生脹圈現(xiàn)象，一般不是彈簧墊圈本身的問題。2.發(fā)生脹圈的彈簧墊圈必然受到一個徑向外張力，外張力源于擰緊力矩產(chǎn)生的加緊軸力。3.螺母支承面的外倒角使軸向夾緊力產(chǎn)生了徑向分力，從而使得彈簧墊圈的開口脹大。倒角直徑越小，發(fā)生脹圈的可能性就越大4.在螺母和彈簧墊圈之間加一個平墊圈有助于減緩或者阻止脹圈現(xiàn)象的發(fā)生，但是平墊圈太薄或者太軟也不能防止發(fā)生脹圈5.彈簧墊圈氫脆斷裂原因一般都是有熱處理工藝不合理還有就是電鍍鋅后沒有及時做去氫處理才導致的斷裂。</p><p style="text-indent:25px">對于沒有標準的緊固件，屬于非標件，則需要提供圖紙。比如說GB93彈簧墊圈，這是品名。不過較準確的做法，還是需要稱呼標準，因為DIN127也同樣是這樣的品名；但兩個標準有很多地方尺寸并不一致。墊圈可通過多種方式幫助螺紋緊固件，特別是通過有效地分配和保持夾緊載荷，并防止緊固件移動或腐蝕。對普通大眾而言，墊圈只是一種廉價的金屬圓盤，可保持螺釘，螺栓和螺母的緊固連接。但是對于制造商而言，墊圈是至關(guān)重要的緊固組件，可以專門被設(shè)計用于執(zhí)行獨特的功能并確保可靠的螺栓連接。組合密封墊圈供螺紋管接頭及螺塞密封用。</p><div

style="text-indent:25px">平墊圈DIN125主要用于減小壓強，當有的部位擰緊軸向力很大時，易使墊圈壓成碟形，這時可改用材料和提高硬度來解決。彈簧墊圈DIN127B的鎖緊效果一般，重要部位盡量少用或不用，而采用自鎖結(jié)構(gòu)。對于用于高速擰緊（氣動或電動）的彈簧墊圈，較好采用表面磷化處理的墊圈，提高其減磨性能，否則易摩擦發(fā)熱而燒壞或張口，甚至損壞被連接件表面。對于薄板連接處，不應(yīng)采用彈簧墊圈結(jié)構(gòu)。據(jù)統(tǒng)計，彈簧墊圈在汽車上使用得越來越少了。齒形彈性墊圈中的連接齒形由于鎖緊力大而且均勻，在汽車行業(yè)中使用較多，而間隔齒型的則少一些。對于彈簧墊圈、彈性墊圈，根據(jù)國標，一般可選擇GB699-1999《優(yōu)良碳素結(jié)構(gòu)鋼》中的60、70鋼和65Mn鋼。平墊圈用料：無機械性能要求的平墊圈一般用角料制造。t型墊片批發(fā)</p><p style="text-indent:25px">墊圈是指墊在被連接件與螺母之間的零件。加大墊片廠商</p><p style="text-indent:25px">平墊圈GB97用料：無機械性能要求的平墊圈一般用角料制造，如Q235A，有硬度要求但不高時可以用較厚板料壓延一下達到要求的硬度。彈墊等防松用的墊圈一般用65Mn70#或S50CM—S70CM制造，要經(jīng)過熱處理(淬火+回火)鉚釘、銷軸類：鉚釘、銷軸類一般用料與螺栓相同，但有些鉚釘硬度不可太高，甚至有些要求HRB60以下，一般正常化材料硬度在HRB70-80，因此有些要經(jīng)過退火才能達到性能要求。自攻釘一般用C1018C1020C1022等材料，但國內(nèi)有些廠家為節(jié)約成本，偷工減料，采用18#15#20#更用些廠家用Q235A，然后表面滲碳處理完事，這樣制成的自攻釘其心部的韌性達不到要求，易斷。不銹鋼緊固件了解不多，好像SUS304是很常用的。加大墊片廠商</p><p
