65mn鋼管和45mn鋼管的區別

更新時間:2020-03-26 10:44點擊次數:
首先來說65mn和45mn鋼的c、Si、Mn、P、S含量不同,65mn要高于45mn鋼,你可以買本鋼材只是手冊看一下。45mn鋼淬透性、淬硬性低、塑性、韌性、焊接性好,熱軋或正火后韌性更好,可制作不太重要的中、小型滲碳、碳氮共滲件、鍛壓件,如杠桿軸、變速箱變速叉、齒輪,重型機械拉桿、鉤環等。65mn鋼是常用中碳調質鋼,綜合力學性能良好,淬透性低,65mn鋼管、45mn鋼管、水淬時易生裂紋。小型件宜采用調質處理,大型件宜采用正火處理,主要用于制造強度高的運動件,如透平機葉輪、壓縮機活塞。軸、齒輪、齒條、蝸桿等。


  它們通常適用無縫鋼管的 材質,無縫鋼管又分為GB8162、GB8163這兩個常用的,但65mn鋼只有GB8162才有,55mn是機械加工的一種常用材質。


  55mn鋼管含碳量在0.45%左右,含有小量的錳,硅等,硫磷含量較低的優質碳素結構鋼
