HEXGON BAR
EN1A/EN1A – 230M07
EN1A is used for high-speed production of repetition work, where the major requirements are rapid machining and maximum tool life. Cutting speeds on bright drawn free cutting steel bar are considerably above those of ordinary mild quality steel, and components are produced of similar mechanical properties with a far superior surface finish.
TYPICAL USES
For high-speed production of repetition work (E.G. manufacture of bushes, pins, bolts, nuts, studs and couplings) where the major requirements are rapid machining and maximum tool life.
