230M07 Pb, also known as EN1A Pb or 11SMnPb30, is a low carbon, free cutting engineering steel, with added lead for enhanced machinability.
It is most suitable for use in automatic lathes and CNC machines, specifically for manufacturing repetition turned parts, such as nuts, bolts, hydraulic fitting and other precision machined components. 230M07 Pb is designed for high speed machining, ideal for parts requiring significant material removal and close tolerances.
This material is not recommended for welding, or any load bearing applications.
