</p>即使是成分相同的金屬，當生產(chǎn)條件不同或在不同狀態(tài)下，它們的性能也有很大的差別，例如兩塊含碳量均為0.8%的碳鋼，其中一塊是從冶金廠出廠的，硬度為20HRC，另一塊加工成刀具并進行熱處理，硬度可達60HRC以上。造成上述性能差異的主要原因是材料內(nèi)部結(jié)構(gòu)不同，因此掌握金屬和合金的內(nèi)部結(jié)構(gòu)和結(jié)晶規(guī)律，對于合理選材具有重要意義。 <p> 黃色環(huán)氧板用什么切割 </p> <p> 的切割方法是水磨切割，精度高，效率高，而且省人工。 </p> <p> 切割注意控制好公差，預(yù)多不預(yù)少，可以有效減少報廢率。 </p> <p> 環(huán)氧板用高速鋼是不行的燒刀，用復(fù)合刀才行，也是合金的一種，但比合金便宜多了，五金機電城有的。上海偉奮實業(yè)有限公司是一家專業(yè)提供環(huán)氧板的公司，有想法的可以來電咨詢！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
