Abstract (en)
Disclosed is an enamel steel having a high-temperature baking hardenability, comprising chemical elements in mass percentage: C: 0.008-0.020%, Mn: 0.05-0.50%, S: 0.021-0.035%, Alt: 0.005-0.050% or Als: 0.003-0.045%, 0 < N < 0.003%, 0 < O ‰¤ 0.010%, and element Ti in a mass percentage meeting N × Ti ‰¤ 3 × 10 -4 , S × Ti ‰¥ 2 × 10 -3 and Ti ‰¥ 3.43N + 1.5S + 0.02, the balance being Fe and inevitable impurity elements. Also disclosed is a method for manufacturing the above-mentioned enamel steel, comprising the steps of: a liquid iron pretreatment †’ smelting with a converter †’ refining †’ continuous casting †’ hot rolling. The enamel steel having a high-temperature baking hardenability of the present invention has a better formability, a good welding property, an excellent enamelling firing property and a good enamelling property.
