Influence of Sulfur and Manganese Contents on Texture and Fish-scale Resistance of DC03EK Cold-rolled Enamel Steel

摘要：

　　In the this paper,the compositions design with low carbon and addition of sulfur and manganese which can enhance fish-scale resistance by MnS as hydrogen trap was adopted to produce DC03EK cold-rolled enamel steel.The effect of sulfur and manganese contents on formability and fish-scale resistance of DC03EK cold-rolled enamel steel was investigated.Results show that yield strength,ultimate tensile strength,elongation,work hardening exponent and average plastic strain ratio of the steel with sulfur content of 0.024wt% and manganese content of 0.22wt% is 133 MPa,310 MPa,36.8%,0.22 and 1.46,respectively,showing the well formability.And its hydrogen penetration time and diffusion coefficient is higher than 12 min and lower than 9.26×10-7 cm2/s,respectively,showing excellent fish-scale resistance.However,for the steel with sulfur content of 0.012wt% and manganese content of 0.12wt%,even though better formability is obtained,the fish-scale resistance is poor with hydrogen penetration time of 4.7 min and hydrogen diffusion coefficient of 2.36×10-6 cm2/s which is far from the expectation of steel for enamel.
