不銹鋼球440/440C：性能：硬度達(dá)到56—58度，有磁性，耐腐蝕性好，耐磨性和韌性強(qiáng)用途：主要應(yīng)用于軸承、沖壓/液壓件、閥門、密封件制冷設(shè)備、航空航天高精度的機(jī)械件，上海原裝鋼球承諾守信，工藝品，上海原裝鋼球承諾守信、玩具。 </p> <p> <br /> </p> <p>

鋼球按級別一般分為G10、G16、G20、G100、G500、G1000等。假如一顆鋼球的級別是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，公差范圍在+/-9μm。由此可知，一個(gè)鋼球達(dá)到G10級，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，就需要圓度儀測試圓度，扭簧儀測試鋼球的公差等。得出的數(shù)據(jù)，再對照國標(biāo)GB308-2002的標(biāo)準(zhǔn)，就能得出一個(gè)鋼球?qū)儆谀膫€(gè)級別的鋼球。 </p> <p> 哪個(gè)級別的鋼球好呢？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級鋼球較多。但是在實(shí)際生產(chǎn)的情況中，真正的G3級鋼球目前沒有廠家能生產(chǎn)此級別的鋼球。實(shí)際投產(chǎn)中，G5級鋼球是目前級別較好的。 </p><div style="width:100%;text-align:

高頻加熱：常用頻率為（200～300）KHZ，淬硬層深度為（0.5～2.5）mm。 </p> <p> 中頻加熱：常用頻率為（2500～8000）HZ，淬硬層深度為（2～10）mm。 </p> <p> <br /> </p> <p> 工頻加熱：電流頻率為50HZ，不需要頻設(shè)備，城市用交流電即可，硬層深度為（10～20）mm以上，城市用交流電即。 </p> <p> 鋼球感應(yīng)加熱優(yōu)缺點(diǎn)：感應(yīng)加熱表面淬火加熱速度快，生產(chǎn)率高，加熱溫度和淬硬層深度容易控制，鋼球表面氧化和脫碳少，鋼球變形小，可以使全部淬火過程實(shí)現(xiàn)機(jī)械化、自動(dòng)化。 </p><div style="width:100%;text-align: center;"><img
