Abstract (en)

[origin: WO2014170315A1] The invention relates to a cold reduced enamelling steel sheet comprising (in weight ppm unless otherwise indicated) 5≤C≤90; 0.10≤Mn≤0.50 (wt. %); Alas ≤300 (acid soluble Al); O≤35; S≤350; 30≤N≤110; Bmin<B≤Bmax; wherein Bmin= Nx0.80x10.8/14 and Bmax= Nx10.8/14+144/6; 50≤P≤160; in combination with Cumin≤Cu≤Cumax; wherein Cumin = Px1.00x63.6/31 and Cumax = Px2.00x63.6/31 and optionally Si ≤ 190; the balance being Fe and unintentional and/or inevitable impurities, wherein the steel sheet has been continuous annealed, and wherein the steel sheet has a thickness between 0.10 mm and 0.36 mm. The invention also provides a process for producing such steel, and the use of such steel.
