... filler metals with matching chemistries. The widely used Fe-Ni-Cr alloy 800H is a good example. Many heat-resistant cast alloys also do not have matching filler metals. Thus, when no matching chemistry filler metal is available for welding, it is critical to select a filler metal that not only possesses...

... such as chromium, molybdenum, and tungsten are used for this purpose. The addition of small amounts of tin (~0.1 wt%) is also effective in preventing ferrite formation. The heat resistance of cast irons can be increased by alloying with 18 to 20 wt% Ni and 2 to 3 wt% Cr. There are three groupings of alloying...
