Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and i beams for example.
Hot rolled steel sheet texture.
High strength and highly formable hr steel sheet and plate is also easy to drill form and weld.
Hot rolled steel is used in situations where precise shapes and tolerances are not required.
In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa.
When to use hot rolled steel the pros and cons of hot rolled steel come down to strength versus price.
Cold rolled steel is essentially hot rolled steel that has had further processing.

Two patterns of wavy aluminum sheet 3003 h14 are availble in various thickness.
Cold rolled sheets and strips come in various conditions.
Cold rolled steela rolling process at temperatures that.
The rolls induce plastic deformation.
The textured surface of the patterned aluminum sheet 3003 h14 also offers increased rigidity in the material hiding fingerprints and dents and is popular in decorative metal working.
Full hard rolling reduces the thickness by 50 while the others involve less of a reduction.

Cold rolled steel will have closed thickness profile good surface texture and flatness compared with hot rolled steel.
3 x 4 ft.
In addition to the use as is as finished products hot rolled steel sheets are further processed in the cold rolling and annealing proc esses to be used as cold rolled steel sheets.
As an example a hot rolled steel product may have a yield strength of 235 mpa.
5 x 10 ft.
Thus the yield strength of cold rolled steel is higher than that of hot rolled steel.

Hot rolled steel sheet 5 63 lb select.
Alternatively cold rolled steel has sharp edges a very smooth surface texture and an oily or greasy feel to it.
Cold rolled steel is then annealed to induce ductility in the cold rolled steel which is simply known as a cold rolled and close annealed.

Full hard half hard quarter hard and skin rolled.
Hot rolled steel has rounded edges a rough surface texture and no grease on its finish.
Texture formed in a process is taken over by the following manufacturing processes one by one influencing the next process.

When galvanized it is also regularly used in applications where corrosion resistance is a necessity.
Hot rolled steel sheet and plate provides a rougher surface than cold rolled steel and plate.
Aluminum sheet 3003 h14 is corrosion resistant and highly formable.
Hot rolled steel is more malleable allowing it to be forced into a variety of different shapes.
Whereas hot rolled has a grey and scaly finish.
Cold rolled has a smooth and shiny finish.
