Steel Plate - Hot Rolled PlateSteel Plate - Hot Rolled Plate

• Hot Rolled Plate•Metals at temperatures above the recrystallization temperature to a rolling

•Use : Pipe, Automobile-chassis, Container, Cold Rolled Plate

•☆Making Cold Rolled Plate : Washing the Metal with chemical meterial.(like HCl) and rolling the metal on the cold-strip-mill or reverse mill.

-increases the strength via strain hardening and improves the surface finish.

-but more expensive
