For that you need heat treated steel of medium to high carbon content. I suppose it may be possible to work harden steel by continued passes through the rolling mill but I am not aware of any being made commercially. |

If you can heat the steel you can use bright drawn mild steel ( BDMS) but evan with black bar you will get some spring back and you will have to experiment with amount of over bending to get correct angle. Perhaps you can give us a little more info about job. David |
