Hot Rolled Steel Cold Rolled Steel - Difference

Hot Rolled Steel Properties.As it is easy to form metal in high temperatures without any extra delays,it is possible to produce it in larger quantities than cold rolled steel.This keeps the market price of hot rolled steel lower.The steel cools at room temperature.This is known as normalising.Hot Rolled Steel AK SteelHIGH STRENGTH LOW ALLOY STEEL (HSLAS) For high strength or Structural Steel (SS) applications,Hot Rolled Steels are also available (shown in Table 2).HSLAS is intended for applications where greater strength or weight savings are important.The increased strength of HSLAS is achieved from niobium (Nb) or vanadium (V) additions.Hot Rolled Steel Sheet and Plate HR Steel Sheet PlateHot rolled steel sheet and plate provides a rougher surface than cold rolled steel and plate.When galvanized it is also regularly used in applications where corrosion resistance is a necessity.High strength and highly formable HR steel sheet and plate is also easy to drill,form and weld.

Hot Rolled vs Cold Rolled Steel What is the difference

Cold-rolling involves rolling of steel in reduced mills at below recrystallization temperature (room temperature).During cold rolling,hot rolled steel is further processed at room temperature to have a smooth and shiny finish,closed thickness profile,good surface texture and flatness..Cold rolled steel will have higher yield strength and available in the thickness range of 0.1 mm to 4 mm.Hot-rolled steel sheets - JFE Steel Corporation Sheets780/980MPa grade Hot-rolled High Strength Steel Sheets for Chassis Parts Developed steels that demonstrate excellent stretch-flange formability and expand applicable parts of high strength steel.Since suspension parts require severe stretch-flange formability,forming with the conventional 780MPa grade steel sheet was difficult.METHODS OF PRODUCING CONTINUOUSLY CAST HOT ROLLED HIGH Methods of producing high strength continuously cast hot rolled steel sheet products are disclosed.The methods include continuously casting a steel slab and then hot rolling with finish rolling on a hot strip mill,quenching on the hot strip mill to form a predominantly matrensitic microstructure,and performing a thermal cycling step including soaking at an intercritical temperature followed
