鋼球按級(jí)別一般分為G10、G16、G20、G100、G500、G1000等。假如一顆鋼球的級(jí)別是G10，其意味著鋼球的直徑變動(dòng)量在0.25μm，圓度是0.25μm，粗糙度是0.25μm，上海通用鋼球規(guī)格尺寸，公差范圍在+/-9μm。由此可知，一個(gè)鋼球達(dá)到G10級(jí)，證明鋼球的各項(xiàng)參數(shù)均符合G10所包含的范圍。 </p> <p> <br /> </p> <p> 鋼球的等級(jí)既然是由圓度、公差和粗糙度等范圍組合而成，就需要圓度儀測(cè)試圓度，扭簧儀測(cè)試鋼球的公差等。得出的數(shù)據(jù)，再對(duì)照國(guó)標(biāo)GB308-2002的標(biāo)準(zhǔn)，就能得出一個(gè)鋼球?qū)儆谀膫€(gè)級(jí)別的鋼球。 </p> <p> 哪個(gè)級(jí)別的鋼球好呢？按照現(xiàn)代鋼球行業(yè)發(fā)展的現(xiàn)狀，精密鋼球廠中一般生產(chǎn)G10級(jí)鋼球較多。但是在實(shí)際生產(chǎn)的情況中，上海通用鋼球規(guī)格尺寸，上海通用鋼球規(guī)格尺寸，真正的G3級(jí)鋼球目前沒(méi)有廠家能生產(chǎn)此級(jí)別的鋼球。實(shí)際投產(chǎn)中，G5級(jí)鋼球是目前級(jí)別較好的。鋼球外觀檢測(cè)是鋼球加工過(guò)程中不可缺少的過(guò)程。上海通用鋼球規(guī)格尺寸</p><div

鋼球材質(zhì)會(huì)產(chǎn)生影響：鋼球、鑄鐵球、合金鋼球等，不同材質(zhì)的密度不同，鋼的密度比鑄鐵的大，合金鋼則依主要合金元素的密度及含量不同而不同。 </p> <p> 鋼球的制造方法會(huì)產(chǎn)生影響：軋制及鍛打的鋼球其組織致密，故密度大，鑄造的鑄鋼球、鑄鐵球或鑄造合金球等的組織致密，相對(duì)密度小一些。 </p> <p> 鋼球金相組織會(huì)產(chǎn)生影響：馬氏體、奧氏體、貝氏體、鐵素體等不同晶體結(jié)構(gòu)下密度也不相同，對(duì)結(jié)晶細(xì)度也有影響。 </p><p> 鋼球等溫淬火 </p> <p> 將奧氏體化鋼球加熱到320°C并在硝酸鉀的鹽浴中，等溫保持足夠長(zhǎng)的時(shí)間，使之轉(zhuǎn)化為下貝氏體組織，然后取出在空氣中冷卻。下貝氏體組織的強(qiáng)度、硬度較高而韌性良好，提高了鋼球的綜合力學(xué)性能。等溫淬火減小了鋼球與淬火介質(zhì)的溫差，從而減小了淬火應(yīng)力，又由于貝氏體的體積比馬氏體小，而且鋼球內(nèi)外溫度一致，故淬火組織應(yīng)力也小。等溫淬火可以較好減小鋼球變形和開裂傾向。 </p> <p> 鋼球回火 </p> <p> 當(dāng)鋼球全淬成馬氏體再加熱到150°C-170°C回火時(shí)，隨著回火溫度升高，按其內(nèi)部組織結(jié)構(gòu)變化，分四個(gè)階段進(jìn)行： </p> <p> <br /> </p> <p> 1）馬氏體的分解；2）殘余奧氏體的轉(zhuǎn)變；3）碳化物的轉(zhuǎn)變；4）e相狀態(tài)的變化及碳化物的聚集長(zhǎng)大．鋼球的公稱直徑：用來(lái)鑒別球尺寸的直徑值。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

化學(xué)成分不銹鋼的耐蝕性隨含碳量的增加而降低，因此，大多數(shù)不銹鋼的含碳量均較低，***大不超過(guò)1.2%，有些鋼的Wc（含碳量）甚至低于0.03%（如00Cr12）。不銹鋼中的主要合金元素是Cr（鉻），只有當(dāng)Cr含量達(dá)到一定值時(shí)，鋼才有耐蝕性。因此，不銹鋼一般Cr（鉻）含量至少為10.5%。不銹鋼中還含有Ni、Ti、Mn、N、Nb、Mo、Si、Cu等元素用途不銹鋼不易產(chǎn)生腐蝕、點(diǎn)蝕、銹蝕或磨損。不銹鋼還是建筑用金屬材料中強(qiáng)度***高的材料之一。 </p> <p> 由于不銹鋼具有良好的耐腐蝕性，所以它能使結(jié)構(gòu)部件長(zhǎng)久地保持工程設(shè)計(jì)的完整性。含鉻不銹鋼還集機(jī)械強(qiáng)度和高延伸性于一身，易于部件的加工制造，可滿足建筑師和結(jié)構(gòu)設(shè)計(jì)人員的需要。隨著軸承行業(yè)的發(fā)展，我國(guó)鋼球行業(yè)也得到了飛躍式提升。上海小型鋼球服務(wù)放心可靠</p><p
