50Mn2,合金結(jié)構(gòu)鋼。
【主要特性】 這是一種高強(qiáng)度中碳調(diào)質(zhì)錳鋼,它具有高的強(qiáng)度、彈性和耐磨性,同時(shí)淬透性也較高,在油中臨界淬透直徑達(dá)10~28mm,在水中臨界淬透直徑達(dá)24~49mm,可切削性尚可。此鋼經(jīng)調(diào)質(zhì)后可得到較高的綜合力學(xué)性能,但熱處理時(shí)有過熱敏感性及回火脆性,水淬也有產(chǎn)生裂紋的傾向,且對白點(diǎn)敏感,焊接性差,冷變形塑性低?!? 【應(yīng)用舉例】 這種鋼通常是在調(diào)質(zhì)后使用,用于制造高應(yīng)力及磨損條件下工作的零件,制造直徑80mm以下的零件時(shí)鋼的性能與45Cr相近;也可在正火及高溫回火后使用,用于制造中等負(fù)荷、截面尺寸較大的零件。例如:重型機(jī)械上用作滾動軸承中的主軸、軸及大型齒輪;汽車上的傳動花鍵軸以及承受沖擊負(fù)荷的心軸;一般機(jī)械上用作齒輪、蝸桿、齒輪軸、曲軸、連桿等。此外,此鋼還可用來制造板彈簧及平卷簧等。
