Free cutting grades
These steels provide a better machinability, allowing shorter machining times. From simply resulfurized to leaded with addition of selenium, the performance goes with the customer?s application and needs. Their mechanical properties go also with the chemical composition and some restrictions can apply.
Our range of Free-Cutting grades is the perfect result of our long history in steelmaking and the application of the most modern techniques of design and production of high quality products.
The results of independent laboratories like CT-DEC (France) testify the performance of our different grades.
Our leaded steels comply with the RoHS European Directive 2002/95/EC with a maximum content of lead of 0,35%.
Carbon grades
Our Carbon steels are used in the automotive industry as well as in a lot of different applications like machinery. We, as for the Free-Cutting grades try to ?stick? to the market and propose a wide range of carbon content.
The tables here below show the typical analysis of the most common grades. But we are committed to follow the evolution of the needs of our customers and will study all the enquiries for any grade you may need.
