230M07 is usually supplied the untreated and cold finished (cold drawn or centreless turned) condition. It is widely used for the manufacture of components requiring superior surface finish with high production rates. 

230M07 is a very popular grade of low carbon-manganese free cutting 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.
