随着机械工业的不断发展,对16mndg低温管500万彩票的要求也越来越高,如何在材料以及热处理工艺既定的前提下尽量提高金属工件的机械性能及使用寿命,这成为很多热处理行业前沿人士思考并探索的问题。16mndg低温管在热处理工艺之后,其硬度及机械性能均大大提高,但热处理后依然有残存的以下问题:

    1、 残余奥氏体。其比例大约有10%-20%,由于奥氏体很不稳定,当受到外力作用或环境温度改变时,易转变为马氏体,而奥氏体与马氏体的比容不一样,将造成材料的不规则膨胀,降低工件的尺寸精度。
    2、 组织晶粒粗大,材料碳化物固溶过饱和。
    3、 残余内应力。热处理后的残余内应力将降低16mndg低温管500万彩票的疲劳强度以及其他机械性能,在应力释放过程中且易导致工件的变形。

深冷处理使得马氏体填补内部空隙,使得16mndg低温管表面更加密实,使耐磨面积增加,晶格更小,合金成分析出均匀,淬火层深度增加,而且不仅仅是表面,使翻新次数增加,寿命提高。
