230M07 Steel (EN1A)
230M07 steel is a low-carbon mild steel with free-cutting properties suitable for high-production use in automatic lathes and CNC machines.
It is also known as EN1A, a commercial cold-drawn bright mild steel product. This free cutting mild engineering steel alloy is particularly suitable for intricate drilling and machining. It has a maximum stress of 370-480 n/mm² and a minimum yield stress of 240-400 n/mm².
- Free cutting properties for intricate drilling & machining
- Low carbon mild steel for improved weldability and formability
- Lead (Pb) can be added to improve machinability
- Easy to machine, weld, and form
230M07 steel has good machinability, especially in the annealed or normalized condition. Its machinability can be further enhanced using appropriate cutting tools, coolants, and machining parameters. The added lead content further improves machinability. This enhances chip formation and improves the surface finish of the machined parts.
