耐磨性：高頻淬火后的工件耐磨性比普通淬火要高。這主要是由于淬硬層馬氏體晶粒細(xì)小，碳化物彌散度高，以及硬度比較高，表面的高的壓應(yīng)力等綜合的結(jié)果。 </p> <p> 疲勞強(qiáng)度：高、中頻表面淬火使疲勞強(qiáng)度大為提高，缺口敏感性下降。對(duì)同樣材料的工件，硬化層深度在一定范圍內(nèi)，隨硬化層深度增加而疲勞強(qiáng)度增加，但硬化層深度過(guò)深時(shí)表層是壓應(yīng)力，因而硬化層深度增打疲勞強(qiáng)度反而下降，并使工件脆性增加。一般硬化層深δ＝（10～**。較為合適，其中D為工件的有效直徑。

滾珠軸承主要包含四個(gè)基本元件：軸承滾珠（ball）、軸承內(nèi)環(huán)（inner ring）、軸承外環(huán)（outer ring）與軸承保持器（cage or retainer）。 </p> <p> 一般工業(yè)用的滾珠軸承滿足AISI52100的標(biāo)準(zhǔn)，軸承滾珠與軸承環(huán)通常是以高鉻鋼制成，洛氏硬度（Rockwell C- scale hardness）約在61-65之間。鋼球的加工工藝應(yīng)滿足其成品的標(biāo)準(zhǔn)要求，使鋼球具有高壽命、低噪聲、低摩擦力和高可靠性。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

伸線（拔絲）：將線材用拉絲機(jī)拉伸至所需要的線徑； </p> <p> 冷鐓（鍛壓）：將拉好的線材置入鋼球冷鐓機(jī)，由機(jī)內(nèi)的鋼模鐓打成球胚； </p> <p> 光球：光球機(jī)內(nèi)的兩塊鑄鐵磨球圓板將冷鐓球胚子加壓銼磨，去除球胚上的外環(huán)帶和兩極點(diǎn)； </p> <p> 軟球：軟球機(jī)內(nèi)的兩塊鑄鐵磨球圓板將光球球胚子銼磨使球胚子磨成所需球徑及表面粗糙度； </p> <p> 熱處理：將球裝入熱處理爐內(nèi)加以滲碳后淬火再回火使球具有一定的滲碳層及硬度，韌性和壓碎負(fù)荷； </p> <p> 硬磨：研磨機(jī)內(nèi)的砂輪圓板將熱處理球胚加壓磨削，以去除球表面的黑色氧化層及修正球的精度； </p> <p> 精研/拋光清洗：精研：將研磨球胚在精研機(jī)內(nèi)精研磨，使球達(dá)到成品所需要的精度和光潔度；拋光清洗：將球倒入拋光滾桶內(nèi)轉(zhuǎn)動(dòng)并用拋光清洗劑加水清洗使球面清潔光亮； </p> <p> 外觀選別：用人工目測(cè)檢查鋼球表面有無(wú)任何瑕疵，并用千分尺測(cè)量真圓度，批直徑變動(dòng)量及用表面粗糙度儀檢測(cè)表面粗糙度來(lái)作為終檢； </p> <p> 包裝：將鋼球/不銹鋼球/軸承鋼球涂上防銹油后裝入紙箱或編織袋后打包。 </p> <p> 出貨：在客戶有要求的前提下，要按照客戶要求進(jìn)行包裝出貨。鋼球廠生產(chǎn)的鋼球，一般作為軸承配套附屬件使用。江蘇質(zhì)量鋼球服務(wù)為先</p><p style="text-indent:25px">鋼球可以用在各種精密機(jī)械上。江蘇**鋼球貨真價(jià)實(shí)</p><p> 碳鋼球，又叫做碳鋼珠，主要是用Q235原材料生產(chǎn)加工，也就是低碳鋼球，根據(jù)是否熱處理分為兩種：一種是熱處理的，即加火，表層硬度達(dá)到HRC55-65；另一種是不熱處理的，也就是俗稱鐵球。在鋼球中是便宜的，使用范圍也廣，用量比較大。這得益于原材料的性能---碳鋼。 </p> <p> <br /> </p> <p> 那么什么是碳鋼呢？碳鋼，也就是碳素鋼，是指含碳量小于1.35%，除鐵、碳和限量以內(nèi)的硅、錳、磷、硫等雜質(zhì)外，不含其它合金元素的鋼。碳素鋼的性能主要取決于含碳量。含碳量增加，鋼的強(qiáng)度、硬度升高，塑性、韌性和可焊性降低。與其它鋼類相比，碳素鋼使用早，成本低，性能范圍寬，用量大。 </p> <p> 碳鋼根據(jù)含碳量分為低碳鋼（含C量0.04-0.25%），中碳鋼（含C量0.25-0.6%）,高碳鋼（含C量0.6-1.35%）。我們?cè)谔间撉蛏a(chǎn)中主要是用的低碳鋼球，不熱處理的情況下，容易焊接。多用于五金配件，鐵藝等要求比較低的。江蘇**鋼球貨真價(jià)實(shí)</p><p
