一种马氏体耐热不锈钢气体保护焊焊丝
摘要：
一种马氏体耐热不锈钢气体保护焊焊丝，其特征在于所述焊丝的化学成分为，质量百分比：C 0.04～0.15，Si 0.2～0.7，Mn 0.4～1.1，S≤0.01，P≤0.015，Cr 9.8～13，Mo 0.4～1.0，V 0.1～0.5，Ni 1.3～2.0，Fe余量。本发明焊丝焊后经650℃回火2小时后，具有良好的综合性能，σb＝845MPa，σs＝745MPa，Akv＝65J，适合于航空工业及能源领域中燃气轮机等部件用0Cr11Ni2MoVNb马氏体耐热不锈钢的焊接。
摘要（英）：

The invention relates to a martensite stainless steel gas shielded arc welding wire, which is characterized in that the chemical constitution of the welding wire has the mass percentage of: 0.04 to 0.15 of C, 0.2 to 0.7 of Si, 0.4 to 1.1 of Mn, less than or equal to 0.01 of S, less than or equal to 0.015 of P, 9.8 to 13 of Cr, 0.4 to 1.0 of Mo, 0.1 to 0.5 of V, 1.3 to 2.0 of Ni, and rest of Fe. After welding, through temper at 650 DEG C for 2 hours, the welding wire has good combination property, Sigma b is equal to 845MPa, Sigma s is equal to 745MPa, and Akv is equal to 65J, thus the martensite stainless steel gas shielded arc welding wire is suitable for welding the martensite heat-resistant stainless steel for the 0Cr11Ni2MoVNb used parts in the aviation industry and the combustion turbine in the energy field.
