Usually supplied the untreated and cold finished (cold drawn or centreless turned) condition. EN1A is widely used for the manufacture of components requiring superior surface finish with high production rates. 

EN1A is a very popular grade of low carbon-manganese freecutting steel, which is most suitable for the manufacture of repetition turned components, such as nuts, bolts, hydraulic fittings and studs, particularly where intricate drilling and machining operations are involved. It can be case-hardened, producing components with enhanced wear resistance
