Free cutting high speed steel with sulphur

These steel grades give improved machinability improving tool life. The production of these steels has to be carefully monitored in order to achieve uniform distribution of sulphide inclusions throughout all sections with good mechanical properties and excellent machinability.

ORI Martin S.p.A.
Wire rod

Rolling takes place at a controlled temperature using the very latest technology. This allows a smaller grain size to be obtained together with a more fine and even structure. Optimal characteristics for subsequent use in drawing and cold moulding in addition to a higher degree of globularisation after the annealing process.

Hot rolled round bars

Production takes place in a rolling mill at a controlled temperature using the very latest technology which guarantees a fine grain and homogeneous structure; the calibrator finishing block allows bars with restricted dimensional tolerances.

Continuous casting billets

ORI Martin spa sells continuous casting steel billets to rolling mills and hot forgers. The refining process with the degassing station and the casting through submerged nozzles guarantee the supply of billets of high-quality engineering steel.
