Ric Furrer Posted October 7, 2013 Share Posted October 7, 2013 I had a student mis-strike the other weekend and the corner broke off. Notice the corrosion under the face so it was never really welded in place. Note also the HUGE grain to the steel face. I may have this broken bit metallographically polished and chem studied just to see. Ric Quote Link to comment Share on other sites More sharing options...
metal99 Posted October 7, 2013 Share Posted October 7, 2013 Is that a cast steel anvil? That would explain the grain size. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 7, 2013 Share Posted October 7, 2013 Crack has been around a while; but I don't think is was original. The question is what type of build method was that anvil? I'm guessing a cast top; like one of the younger american anvils had. I had a lot of "crush damage" with a trenton that had been abused at a copper mine. When it was gussied up the edge problems were found to extend aways further than we had guessed. Luckily we had a professional welder---who teaches welding, using professional equipment, (optical pyrometer on the preheat!), who is also a highly trained smith who had volunteered for the anvil repair meeting. Used the Gunter method and the 400+# anvil holds down the armouring end of my shop. Quote Link to comment Share on other sites More sharing options...
KYBOY Posted October 7, 2013 Share Posted October 7, 2013 Man, that's monster grain..Looks like some of my early attempts at quenching files from 2250°,LOL Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 7, 2013 Share Posted October 7, 2013 Which could be the result of the forge welding of the face on or of casting, the crack surface doesn't seem to show any forge weld transition which is why I'm thinking a cast top.

MLMartin Posted October 7, 2013 Share Posted October 7, 2013 The shape looks spot on for a Hay Budden. Some Hay Buddens had the entire top of the anvil, waist up forged from steel, and only the bottom was wrought iron. I would guess this is the case, I do not think it is cast steel Quote Link to comment Share on other sites More sharing options...
VaughnT Posted October 8, 2013 Share Posted October 8, 2013 Pre-heat to 450º with a big torch and then hit it with some 7018 rod. There's not a lot of meat missing, and that corner is really out of the way. While 7018 isn't a hard-facing rod, it's plenty strong enough for the occasional errant blow.
