What's the difference between iron sheet and cold-rolled carbon steel plate?

Thin iron sheet, usually a few millimeters, galvanized; The thickness of steel plate, generally above 3mm, also has1mm. ..

Hot rolled steel has low strength, good elongation and dull appearance color. Cold rolled steel has high strength, high hardness and bright surface. Hot rolled steel plate: steel plate rolled after heating (heating temperature is above recrystallization temperature, generally above critical point). Cold-rolled steel: steel plate rolled without heating at normal temperature (strictly speaking, below recrystallization temperature).
