Dentsitate bajuko eta aleazio ertaineko altzairu aleatuak alumioarekin eta manganesoarekin
The present invention is encompassed within the sector of metallurgical industry. Particularly, it relates to a new family of medium alloyed steels with a low density and balanced mechanical properties, such as yield strength, tensile strength and elongation, which avoids the inclusion of costly and scarce alloying elements, such as Cr, Mo, Ni and V. In general, medium alloyed steels are alloys incorporating scarce and costly alloying elements, such as Cr, Mo, Ni and V (chromium, molybdenum, nickel and vanadium, respectively), whereas the alloys according to the present invention comprise Mn and Al (manganese and aluminium, respectively), which are abundant in nature and therefore significatively more affordable.
