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。 </p>

不銹鋼鋼球通常是由不銹鋼鍛造工藝生產(chǎn)的鋼球，現(xiàn)階段常用不銹鋼球的材質(zhì)有201、302、304、316、316L、420、440C。 </p> <p> <br /> </p> <p> 不銹鋼的定義是含有12.5%以上的鉻，具有較高的抵抗化學(xué)物質(zhì)（酸、堿、鹽）腐蝕的鋼材。 </p> <p> <br /> </p> <p> 不銹鋼球的原理是不銹鋼不是不會(huì)生銹，而是不易生銹。其原理是借著鉻元素的添加，在鋼材的表面形成一層組織致密的氧化鉻層，可以有效的阻隔鋼材與空氣的再接觸，使空氣中的氧無法進(jìn)入鋼材內(nèi)，而達(dá)到防止鋼材生銹的效果。 </p> <p> <br /> </p> <p>

</p> <p> 另外，也有利用成份、導(dǎo)磁性、能否熱處理硬化及鋼種編號(hào)來分類。 </p><p> 鋼球低溫回火： </p> <p> 低溫回火又稱“消除應(yīng)力回火”?；鼗饻囟确秶鸀?50-250攝氏度，回火后的組織為回火馬氏體。鋼具有高硬度和高耐磨性，但內(nèi)應(yīng)力和脆性降低。經(jīng)滲碳和表面淬火的零件，回火后的硬度一般為58-64HRC。
