Bigcity Posted December 21, 2009 Share Posted December 21, 2009 i was working on a tamahawk head out of a file i think i had gotten it to weld it just a wrap around with no bit and i had it crack i was wondering if file steel is kinda brittle to forge or if it needs to be at a certin temp to forge? i got pics ill get them posted in abit Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted December 21, 2009 Share Posted December 21, 2009 File steel is generally easy to overheat and crack and easy to crack in quenching. That looks like an over heat crack to me. Did you weld it like it was a low carbon steel? (May be too hot for a real high carbon steel like a file) Quote Link to comment Share on other sites More sharing options...
Frank Turley Posted December 21, 2009 Share Posted December 21, 2009 In a blacksmith forge situation, any file steel or high carbon steel needs to be welded at a "sweating heat," no sparks. Otherwiae, it can crack and/or crumble.Turley Forge and Blacksmithing School : The Granddaddy of Blacksmithing Schools Quote Link to comment Share on other sites More sharing options...
Bigcity Posted December 22, 2009 Author Share Posted December 22, 2009 ok that is like my 2nd time welding in my forge i tryed to get it to sparking heat and that might be my problem Quote Link to comment Share on other sites More sharing options...
Bigcity Posted December 30, 2009 Author Share Posted December 30, 2009 ok i finaly got some leaf springs from the local spring shop i know they are high carbon but do you need to weld spring steel at a sweating heat or a sparking heat?

ThomasPowers Posted December 30, 2009 Share Posted December 30, 2009 leaf springs are usually *medium* carbon steel, like 5160. They do harden deeper due to alloying though. I generally weld knife grade steels below sparking and only real wrought iron at a snowball heat! Quote Link to comment Share on other sites More sharing options...
