1Cr11Ni2W2MoV martensitic stainless were joined using Cu58MnCo filler metal. Influence of brazing temperature, holding time and working atmosphere on microstructure and properties of joints were studied. It indicated that α'+[γ(Fe),γ(Mn)] phase, α(Co)+δ phase and[Cu,γ(Mn)]+α(Mn) phase were observed in the joints. When brazing temperature or holding time was over high or long, the counts of α'+[γ(Fe),γ(Mn)] phase and[Cu,γ(Mn)]+α(Mn) phase increased, α(Co)+δ phase decreased, and the mechanical properties decreased. The properties of brazing joint get in 70 Pa better than in 1×10-2 Pa.
