    PROPERTIES

    Machinability:
    This steel grade is marked by a good machinability on machine tools and by an easy fragmentation of chips.

    Weldability:
    Due to the high sulphur and phophorus content free-cutting steels not destined to heat treatment are not generally recommended for welding.
