The present invention relates an iron based brazing material comprising an 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 to 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 wt% of each of one or more of elements selected from the group consisting of carbon (C), vanadium (V), titanium (Ti), tungsten (W), aluminium (Al), niobium (Nb), hafnium (Hf), and tantalum (Ta); the alloy being balanced with Fe, and small inevitable amounts of contaminating elements; and wherein Si, B and 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 method of brazing article of stainless steel, and an article of stainless steel. ® KIPO & WIPO 2009 |
