All SSAB Laser® steels are aluminum-killed (Al ≥ 0.015%) and grain-refined. Additionally, niobium (Nb), vanadium (V), titanium (Ti) and/or boron (B) may be used as single alloying element or in any combination.
All SSAB Laser® products are delivered with SSAB Laser® tolerances, which means increased guarantees compared to corresponding EN standards. Detailed information is available on ssab.com.
Hot rolled sheet: SSAB Laser® tolerances correspond to ⅔ of EN 10051 as default. Tighter tolerances are available upon request.
Hot rolled plate: SSAB Laser® tolerances correspond to ¾ of EN 10029 as default.
Hot rolled sheet: -0/+20 mm for mill edge sheet; -0/+2 mm for cut edge sheet. Tighter tolerances are available upon request.
Hot rolled plate: -0/+4-10mm depending on the thickness.
