Abstract
A nickel-plated heat-treated steel sheet having excellent workability and a method of manufacturing the same. The nickel-plated heat-treated steel sheet includes: a base steel sheet; a nickel layer formed on one or both surfaces of the base steel sheet; and a nickel-iron (Ni—Fe) alloy layer formed between the base steel sheet and the nickel layer, and has a superficial Rockwell hardness of about 52 to about 62.
Claims4
A nickel-plated heat-treated steel sheet comprising:
- a base steel sheet;
- a nickel layer formed on at least one surface of the base steel sheet;
- and
- a nickel-iron (Ni—Fe) alloy layer formed between the base steel sheet and the nickel layer,
- the nickel-plated heat-treated steel sheet having a superficial Rockwell hardness of about 52 to about 62.
