How to differentiate them? Hot rolled steel comes with a scaly surface, slightly rounded edges and corners and the surface is non-oily. Cold rolled steel has an oily or greasy finish, very smooth surface, and very sharp edges.

Is hot rolled or cold rolled steel stronger?
In terms of physical characteristics, cold rolled steels are typically harder and stronger than standard hot rolled steels. As the metal is shaped at the lower temperatures, the steel's hardness, resistance against tension breaking, and resistance against deformation are all increased due to work hardening.
Which is more expensive hot rolled or cold rolled steel?
Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled). ... Hot rolled steel is used in situations where precise shapes and tolerances are not required.
What is easier to weld cold rolled or hot rolled steel?
Hot rolled surface is black oxide (the "black" in blacksmith) the surface has texture and the material is a little softer. Welding won't be as apparent, cold working is easier and hot working, if you go in that direction will leave a similar surface.
What is cold rolled steel used for?
Common Cold Rolled Steel Products
This makes it ideal for use in many home appliances and metal furniture. Metal filing cabinets and school lockers are commonly made of this metal. In construction, Cold Rolled Steel is a common material for building steel sheds, industrial buildings, and garages.
Why is cold rolled steel more expensive?
Price: Because of its advantages over hot rolled steel, cold rolled steel is more expensive. Also, because cold rolled steel is tougher to manipulate, it's takes more time and can cost more to take it through similar processes.
Does cold rolled steel rust?
ASTM A1008 Cold Rolled Steel. Cold Rolled Steel is a mill product made with a high degree of gauge accuracy and uniformity of physical characteristics. ... Because cold rolled steel sheet is prone to rusting, standard practice is to apply a rust-preventative oil at the exit end of the temper mill (the last processing step) ...
How strong is hot rolled steel?
Cold rolled has a tensile strength of 85,000 psi while hot-rolled steel has 67,000 psi.
Will hot rolled steel rust?
The variations of color along the steel sheets provide for character throughout the sculpture. The down side to hot roll dry is that because it does not have a finish it is prone to rusting.
Is A36 hot or cold rolled?
ASTM A36 steel is the most commonly available of the hot-rolled steels. It is generally available in square bar, rectangle bar, as well as steel shapes such as I-Beams, H-beams, angles, and channels. The hot roll process means that the surface on this steel will be somewhat rough.
What are three advantages to cold rolled steel?
The Benefits of Cold-Rolled Steel
- Increased Strength. Cold-rolled steel is significantly stronger than hot-rolled steel. ...
- Improved Surface Finish. In addition to being stronger, cold-rolled steel has an improved surface finish. ...
- Tighter Tolerances. ...
- Multiple Options. ...
- What Are the Disadvantages of Cold-Rolled Steel?
What are three advantages of hot rolled steel?
Hot rolling can greatly reduce energy consumption and costs. The metal plastic deformation is high during hot rolling, and the deformation resistance is low, which reduces the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys.
Can hot rolled steel be welded to cold rolled steel?
If you're planning on welding, both hot and cold rolled metals will weld just fine – but keep in mind that cold rolled metal will take on the appearance, and some of the other characteristics of hot rolled metal after being welded.
