style="text-indent:25px">對圓鋼的晶粒度和淬透性的影響：影響奧氏體晶粒度的因素很多。圓鋼的脫氧和合金化情況均與“奧氏體本質(zhì)晶粒度”有關(guān)。一般來說,一些不形成碳化物的元素,如鎳、硅、銅、鈷等,阻止奧氏體晶粒長大的作用較弱,而錳、磷則有促進(jìn)晶粒長大的傾向。碳化物形成元素如鎢、鉬、鉻等，對阻止奧氏體晶粒長大起中等作用。強(qiáng)碳化物形成元素如釩、鈦、鈮、鋯等，強(qiáng)烈地阻止奧氏體晶粒長大，起細(xì)化晶粒作用。鋁雖然屬于不形成碳化物元素，但卻是細(xì)化晶粒和控制晶粒開始粗化溫度的較常用的元素。合金圓鋼洛氏硬度試驗(yàn)同布氏硬度試驗(yàn)一樣，都是壓痕試驗(yàn)方法。山東T10A圓鋼</p><p style="text-indent:25px">在建筑應(yīng)用領(lǐng)域，合金圓鋼的表面加工之所以重要是有許多原因的。鎮(zhèn)江50crv圓鋼代理</p><p style="text-indent:25px">圓鋼與其它鋼筋的區(qū)別：1、外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。2、成份不一樣，圓鋼(一級鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。3、強(qiáng)度不一樣，圓鋼強(qiáng)度低，其它鋼強(qiáng)度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強(qiáng)，即圓鋼在被拉斷前有較大的變形，而其它鋼筋在被拉斷前的變形要小得多。鎮(zhèn)江50crv圓鋼代理</p></p><br
