2014 09 11 nbsp 0183 32 The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill and not the product specification or grade Hot rolled steel involves rolling the steel at high temperatures where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by annealing and or tempers rolling
Cold rolled steel is stored and sold in coiled form after rolling Steel comes in many grades specifications shapes and finishes the World Steel Association lists over 3 500 different grades of steel each with unique properties The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications
2012 10 12 nbsp 0183 32 Cold rolled steel is more expensive than hot rolled it is typically 1018 alloy steel It is descaled and rolled cold this gives it a silvery finish and it is more precisely sized than hot rolled It is work hardened from the cold rolling process this can make cold work difficult it tends to be easier to forge hot than hot rolled A36 due to its lower carbon and alloy content Hot

Hot rolled and cold rolled steels are mild containing from 0 1 to 0 3 carbon Such chemical composition makes them suitable for welding The less carbon the material has the easier it is to weld It allows welders to use any methods and techniques when working with these steels 3 Reasons Why Hot Rolled Steel Is Easier to Weld Still hot rolled metal might be a better
2022 01 10 nbsp 0183 32 Hot Rolled Steel Vs Cold Rolled Steel An Overview Hot and Cold Rolled steels are two distinctive types of metals because of how they are manufactured Hot Rolled Steel is treated at a high temperature of 1700℉ 930℃ which alters its material properties Contrary to this Cold Rolling process comes after this and is done below the recrystallization temperature
Hot Rolled vs Cold Rolled Steel The Differences First off it s important to note that the primary difference between hot and cold rolled steel is the process of how it gets manufactured Hot rolling is when you process the steel with heat and cold rolling is when you process the steel at or near room temperature While these manufacturing techniques affect the steel s overall
