style="text-indent:25px">對(duì)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(lái)說(shuō),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(zhǎng)大的作用較弱,而錳、磷則有促進(jìn)晶粒長(zhǎng)大的傾向。碳化物形成元素如鎢、鉬、鉻等，對(duì)阻止奧氏體晶粒長(zhǎng)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(zhǎng)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。</p><p style="text-indent:25px">合金圓鋼是一種很難進(jìn)行切削加工的管材，合金圓鋼由于具有很大的粘性和快速冷作硬化的傾向，加工難度極大。雖然具有很好的韌性和強(qiáng)度，但也極易發(fā)生冷作硬化。而在進(jìn)行攻絲上也常常出現(xiàn)一些問(wèn)題。合金圓鋼攻絲的問(wèn)題通常表現(xiàn)為螺紋粗糙和破損、工件材料咬死絲錐并導(dǎo)致其折斷。絲錐本身的缺點(diǎn)(如切削刃幾何形狀不正確、基體材料和涂層選用不當(dāng))可能是根本的原因。不過(guò)，通常還有一些其他原因。合金圓鋼的攻絲加工需要使用具有高潤(rùn)滑性的冷卻液。攻絲通常是切削負(fù)荷的加工方式之一，如果冷卻液的潤(rùn)滑性不足，其不利影響將比大多數(shù)其他加工更快地顯現(xiàn)出來(lái)。構(gòu)成合金圓鋼的元素有很多種，并且對(duì)合金圓鋼性能有很大的影響。</p><div

style="text-indent:25px">圓鋼的耐磨性：決定模具使用壽命較重要的因素往往是模具材料的耐磨性。模具在工作中承受相當(dāng)大的壓應(yīng)力和摩擦力，要求模具能夠在強(qiáng)烈摩擦下仍保持其尺寸精度。模具的磨損主要是機(jī)械磨損、氧化磨損和熔融磨損三種類型。為了改善圓鋼的耐磨性，就要既保持圓鋼具有高的硬度，又要保證鋼中碳化物或其他硬化相的組成、形貌和分布比較合理。對(duì)于重載、高速磨損條件下服役的模具，要求圓鋼表面能形成薄而致密粘附性好的氧化膜，保持潤(rùn)滑作用，減少模具和工件之間產(chǎn)生粘咬、焊合等熔融磨損，又能減少模具表面進(jìn)行氧化造成氧化磨損。所以模具的工作條件對(duì)鋼的磨損有較大的影響。合金圓鋼在氯離子存在下的環(huán)境中，腐蝕很快。蕪湖f22圓鋼定制</p><p
