EN1A Round Bar
EN1A Rod
EN1A Leaded Round Bar
EN1A is also available as leaded (EN1A Pb) for enhanced machinability. Usually supplied the untreated and cold finished (cold drawn or centreless turned) condition. EN1A is widely used for the manufacturing 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 bolts, nuts, studs and hydraulic fittings, particularly where intricate drilling and machining operations are involved. It can be case-hardened, producing components with enhanced wear resistance
EN1A Leaded / EN1APb also known as 230M07Pb. A low carbon mild steel with added lead. Properties: free cutting, suitable for machining using both automatic and CNC machines. Available in square, round, flat or hexagon form. AISI 12L14
