介绍 | Tenaris produces HB 470 AR, HB 420 N and HB 590 QT grades in CMnV micro-alloyed steel for applications requiring high values of yield strength and very good impact test values when normalised or quenched and tempered. Notwithstanding the high yield strength values of these products, the specific inclusional environment designed by Tenaris and the strict control of the operative conditions in the steel plant, guarantee an excellent tool life and high cutting speeds. These products can be supplied in"as rolled" (AR), normalized (N) or quenched and tempered (QT) conditions. |
