High Sulfur Lead Alloyed Free-Cutting Steel with Excellent Machinability

Free-cutting steel with the addition of lead similar to the previous one, but with a higher sulfur content. It is the most common type in Italy and France and it provides excellent machinability. The Telyx version has a further improved machinability with respect to PS113.
