En1a steel sheet.
En1apb 230m07pb is a low carbon leaded free cutting steel bright drawn or smooth turned with a consistently excellent level of machinability.
The alloy can be case hardened which improves wear resistance and has reasonable strength and ductility.
This steel is especially good for free cutting where a large volume of products are required.
It is presented apart from.
It can be formed by rolling or drawing and the machining of en1a is fine of both automatic and cnc machines.
En1a engineering steel is ideal for use in precision turned components and is used in intricate drilling and machining operations.
