Enamel steel having high-temperature baking hardenability. The enamel steel comprises chemical elements in mass percentage as follows: 0.008%-0.020% of C, 0.05%-0.50% of Mn, 0.021%-0.035% of S, 0.005%-0.050% of Alt or 0.003%-0.045% of AlS, greater than 0 and less than 0.003% of N, greater than 0 and less than or equal to 0.010% of O, and element Ti, wherein the weight percentage of element Ti meets the conditions N×Ti≤3×10-4, S×Ti≥2×10-3 and Ti≥3.43N+1.5S+0.02, and the balance is Fe and unavoidable impurity elements. A manufacturing method for the enamel steel, which comprises the steps of pretreatment of hot metal, converter smelting, refining, continuous casting and hot rolling. The enamel steel having high-temperature baking hardenability has relatively good forming property, good welding property, excellent firing property and excellent enameling property. |
