LABOR Pb material is
Manufactured in Rod, Bar and coil
WS 1.1268 +Pb Steel - Hardenable
Free Cutting
Material Features
Law 100Pb combines the
characteristics of a pure tool steel and a free-cutting steel, in order to
improve the toughness the S-content is not as high as with a pure
free-cutting steel. The machining properties have not only been
improved by the S and Pb content, but by distinct measures taken during
melting and heat treatment of the steel and with help of a favorable
balanced tensile range in cold drawn execution adapted to the final sizes.
