Final answer:
Hot-rolled steel does not have a thin copper layer formed during the rolling process.
Step-by-step explanation:
False. Hot-rolled steel does not have a thin copper layer formed during the rolling process. Copper is not typically used in the manufacturing process of hot-rolled steel. Hot-rolled steel is produced by heating the steel material above its recrystallization temperature and then rolling it into the desired shape. The process does not involve the addition of a copper layer.
