The present invention relates an iron based brazing material comprising a n alloy consisting essentially of: 15 to 30 wt% chromium (Cr); 0 to 5.0 wt% manganese (Mn); 15 to 30 wt% nickel (Ni); 1.0 to 12 wt% molybdenum (Mo); 0 t o 4.0 wt% copper (Cu); 0 to 1.0 wt% nitrogen (N); 0 to 20 wt% silicone (Si); 0 to 2.0 wt% boron (B); 0 to 16 wt% phosphorus (P); optionally 0.0 to 2.5 w t% of each of one or more of elements selected from the group consisting of carbon (C), vanadium (V), titanium (Ti), tungsten (W), aluminium (Al), niobi um (Nb), hafnium (Hf), and tantalum (Ta); the alloy being balanced with Fe, and small inevitable amounts of contaminating elements; and wherein Si, B an d P are in amounts effective to lower melting temperature, and Si, B, and P are contained in amounts according to the following formula: Index = wt% P + 1.1 x wt% Si + 3 x wt% B, and the value of the Index is within the range of from about 5 wt% to about 20. The present invention relates also to a metho d of brazing article of stainless steel, and an article of stainless steel.< /SDOAB> |
