多發(fā)生在含Mn、Cr、Ni等元素的合金鋼中。這是一種可逆回火脆性, 回火后快冷（通常用油冷）可防止其發(fā)生。鋼中加入適當Mo或W（0.5%Mo, 1%W）也可基本上消除這類脆性。馬鞍山12Cr1MoV合金板合金板厚的寬度為600~3000毫米.厚鋼板的鋼種大體上和薄鋼板相同。</p><div style="width:100%;text-align: center;"><img

2.鋼板按軋制分，分熱軋的和冷軋的。按用途分類：橋梁鋼板（2）鍋爐鋼板（3）造船鋼板（4）裝甲鋼板（5）汽車鋼板（6）屋面鋼板（7）結構鋼板（8）電工鋼板（硅鋼片）（9）彈簧鋼板（10）其他</p><p style="text-indent:25px">沸騰合金鋼板大量用于制造各種沖壓件，建筑及工程結構及一些不太重要的機器結構零部件。但沸騰鋼心部雜質較多，偏析較嚴重，組織不致密，力學性能不均勻。同時由于鋼中氣體含量較多，故韌性低，冷脆和時效敏感性較大，焊接性能也較差。故沸騰鋼板不適于制造承受沖擊載荷、在低溫條件下工作的焊接結構及其他重要結構。鎮(zhèn) 靜鋼板是由普通碳素結構鋼鎮(zhèn) 靜鋼熱軋制成的鋼板。鎮(zhèn) 靜鋼是脫氧完全的鋼，鋼液在澆注前用錳鐵、硅鐵和鋁等進行充分脫氧，鋼液含氧量低（一般為0.002-0.003%），鋼液在鋼錠模中較平靜，不產生沸騰現象，鎮(zhèn) 靜合金鋼由此得名。合金鋼板按合金元素成分：鉻鋼、鉻鎳鋼、錳鋼、硅錳鋼。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">合金板按結構分類：壓力容器用鋼板：用大寫R在牌號尾表示，其牌號可用屈服點也可用含碳量或含合金元素表示。如：Q345R，Q345為屈服點。再如：20R、16MnR、15MnVR、15MnVNR、8MnMoNbR、MnNiMoNbR、15CrMoR等均用含碳量或含合金元素來表示。焊接氣瓶用鋼板：用大寫HP在牌號尾表示，其牌號可以用屈服點表示，如：Q295HP、Q345HP；也可用含合金元素來表示如：16MnREHP。鍋爐用鋼板：用小寫g在牌號尾表示。其牌號可用屈服點表示，如：Q390g；也可用含碳量或含合金元素來表示，如20g、22Mng、15CrMog、16Mng、19Mng、13MnNiCrMoNbg、12Cr1MoVg等。橋梁用鋼板：用小寫q在牌號尾表示，如Q420q、16Mnq、14MnNbq等。汽車大梁用鋼板：用大寫L在牌號尾表示，如09MnREL、06TiL、08TiL、10TiL、09SiVL、16MnL、16MnREL等。合金鎮(zhèn) 靜鋼板是脫氧完全的鋼，鋼液在澆注前用錳鐵、硅鐵和鋁等進行充分脫氧。馬鞍山12Cr1MoV合金板</p><p style="text-indent:25px">合金板在高溫下具有較高的熱強性（δb≥440MPa）和抗氧化性。馬鞍山12Cr1MoV合金板</p><p style="text-indent:25px">但是合金元素在退火狀態(tài)下, 合金鋼沒有很大的優(yōu)越性。由于過冷奧氏體穩(wěn)定性增大, 合金鋼在正火狀態(tài)下可得到層片距離更小的珠光體, 或貝氏體甚至馬氏體組織, 從而強度大為增加。Mn、Cr、Cu的強化作用較大, 而Si、Al、V、Mo等在一般含量（例如一般結構鋼的實際含量）下影響很小。對淬火、回火狀態(tài)下鋼的機械性能的影響：合金元素對淬火、回火狀態(tài)下鋼的強化作用比較明顯, 因為它充分利用了全部的四種強化機制。淬火時形成馬氏體, 回火時析出碳化物, 造成強烈的第二相強化，同時使韌性極大改善, 故獲得馬氏體并對其回火是鋼的比較經濟和比較有效的綜合強化方法。馬鞍山12Cr1MoV合金板</p></p><br /><p>文章來源地址:
