| DaveH:
Hi, Key steel is EN8/EN9 roughly BMS is EN3, I have always tended to use Key steel because it seemed to machine better and I thought less prone to warping. Now in my (as so eloquently pointed out by a member who shall rename nameless - HS93) old age I'm not so sure it is true. Anyone has any views. I'd be interested to hear what you you have to say. For a start is key steel worth the extra cost. :beer: DaveH |

I think Bright Mild Steel covers several grades of steel including EN1A EN1A's lead content makes it free cutting , great when machining but no use if you want to weld it John |
