Cast steel and cast iron are two very different animals. TIG brazing with silicon bronze filler rod works very very well for repairing cast iron. I have done it on several occasions, most notably on a cracked milling machine casting. 10 years and a lot of use later none of the brazed cracks have caused problems.
