(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.

Standard availability
Ø< 3.00mm: decarb free cold drawn and polished
Ø>= 3.00mm: decarb free cold drawn and ground polished.

Tolerances
Standard ISO h7, up to +/- 0.002mm on request in short time available out of roundness: 1/2 of dia tol

Tensile strength Rm: approx 650-950 N/mm2 depending on the dimension

Heat Treatment:
Hardening Temp 800-820ºC (up to dia 5.00mm)
780-800ºC ( above dia 5.00mm)
quenching in oil (oil temp) 50-60ºC slow furnace cooling max

Obtainable hardness
64-66 HR

Cutting Rate
55 to 65 m/min (approx value, depending on the lubrication oil, cutting tools, sharpe of parts)

Stock Range
Ø 0.50 to 9.50mm
