Cold reduced enamelling steel sheet and an enamelled structure comprising a component of such a steel sheet

摘要

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 A1); O ≤ 35; S ≤ 350; 30 ≤ N ≤ 110; Bmin < B ≤ Bmax; wherein Bmin = Nx0.80x10.8/14 and Bmax = Nx10.8/14 + 144/6; and optionally Si ≤ 90; 50 ≤ P ≤ 160; in combination with Cumin≤ Cu ≤ Cumax; wherein Cumin = Px1.00x63.6/31 and Cumax = Px2.00x63.6/31; in each case the balance being Fe and unintentional and/or inevitable impurities.
