11L17 Steel Bar - CF
Alro stocks 11L17 Cold Finished Bar - a resulphurized steel with good machine-ability and surface finish. The product is made much the same way as 12L14 where the lead does not alloy with the steel. Lead is retained in its elemental state and is dispersed within the steel's structure allowing chips to break off easier during machining.
