Description

This is a special steel designed for use for high speed machining thanks to its high machinability index. 11SMnPb37 is supplied in rolled bars, peeled bars or drawn bars to improve its strength and machinability. It is used to produce small parts, turned or machined parts with removal of swarf, intended for uses which do not require high mechanical properties.
