中文摘要：介绍了1Cr11Ni2W2MoV不锈钢在多用炉中低温气体渗碳的方法，解决了该材料低温渗碳层不均匀的问题。结果表明：零件渗碳前经吹砂或磷化，渗碳时通入NH3，能够保证渗碳层均匀。
英文摘要：The gas carburizing process at low temperature in multi-furnace for 1Cr11Ni2W2MoV stainless steel was introduced. The problem of non uniform carburizing coating was solved. The results show that the carburized case uniformity can be ensured through sand blasting or phosphating before carburizing, and NH3 is filled during carburizing.
