Steel grades for quenching and tempering

They consist of construction steels used in all industrial sectors, especially in the mechanical industry, to produce highly stressed-fatigue components. 

Our casting and rolling techniques allow for steel with excellent hardenability to be achieved together with high micro-purity, controlled austenitic grain and no surface decarburisation. 

The analytical homogeneity associated with an inclusional state suitable for every specific application, guarantees repeatability of the results in the final processes of the clients.

ORI Martin S.p.A.
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.
