style="text-indent:25px">對(duì)圓鋼的力學(xué)性能和回火性能的影響：圓鋼的性能取決于鐵的固溶體和碳化物各自性能以及它們相對(duì)分布的狀態(tài)。合金元素對(duì)圓鋼的力學(xué)性能的影響也與此有關(guān)。固溶于鐵素體中的合金元素，起固溶強(qiáng)化作用，使強(qiáng)度和硬度提高，但同時(shí)使韌性和塑性相對(duì)地降低。圓鋼的淬透性（見淬火）高低主要取決于化學(xué)成分和晶粒度。除鈷和鋁等元素外，大部分合金元素溶入固溶體后都不同程度地控制過(guò)冷奧氏體向珠光體和貝氏體的相變，增加獲得馬氏體組織的數(shù)量，即提高圓鋼的淬透性。合金圓鋼生產(chǎn)時(shí)工作人員要戴護(hù)目鏡。滁州1.4241圓鋼訂做</p><p
