Zusammenfassung: | The invention discloses an electro-galvanized fingerprint-resistant coating steel plate for preventing mold powder adhesion and a manufacturing method thereof.The steel plate comprises a steel billet, a zinc coating wrapping the surface of the steel billet and a fingerprint-resistant film wrapping the surface of the zinc coating, and the steel plate comprises, by weight, less than or equal to 0.002% of C, less than or equal to 0.01% of Si, 0.06-0.12% of Mn, less than or equal to 0.012% of P, less than or equal to 0.009% of S, 0.065-0.085% of Ti, 0.02-0.05% of Als, less than or equal to 0.003% of N and the balance Fe and inevitable impurities. And the balance of Fe and inevitable impurities. After the product is subjected to high-speed and large-deformation stamping, the surface of the product is resistant to abrasion and free of obvious powder falling, the powder sticking situation of the product on a mold after machining is greatly reduced, the shutdown mold wiping frequency of a client side is greatly reduc |
