PORCELAIN ENAMEL STEEL SHEET EXCELLENT IN FISH SCALE RESISTANCE AND ENAMEL ADHESION PROPERTY AND MANUFACTURING METHOD THEREOF

摘要

Disclosed is a cold rolled steel sheet having excellent fish-scale and enamel adhesion by blocking the internal penetration of hydrogen generated on the surface during the enamel firing process as well as the use of a hydrogen storage source existing therein and a method for manufacturing the same. The steel sheet for enamel having excellent fish scale resistance and enamel adhesion according to an embodiment of the present invention is in weight%, C: more than 0 and 0.003% or less, N: 0.007 to 0.01%, Ti: 0.08 to 0.12%, Cr: It contains 3.0 to 5.0%, the remaining Fe and unavoidable impurities, and the value of the following formula (1) satisfies the range of 1,000 to 5,000. (1) (Ti+Cr)/C
