Hot rolled dry steel is hot rolled steel that has not yet gone through a finishing process such as pickle and oiling. This steel has a flaky surface much likes scales called mill scales. This is due to surface oxides such as iron oxide, or rust. Hot rolled dry is more likely to rust and have a rough surface due to its lack of finish.
This steel is typically used in art sculptures due to its unique surface and texture. It is also used in trucks and some automobiles, such as dump trucks after the mill scale has been removed. This is because these trucks are used to get a job done rather than for aesthetics.
The finishing process of hot rolled steel usually makes it easier to machine and weld, so hot rolled dry steel may be harder to machine and weld. It is more likely to crack without going through the pickling and oiling processes.
Advantages:
Disadvantages
While finished hot rolled steel is used in a wide variety of industries due to its aesthetics, hot rolled dry has a more rough surface that makes it less appealing to these industries. This steel is typically used in artistic industries to give art pieces a unique look. It is also used in the automobile industry for trucks that don’t need to be aesthetically pleasing.
Hot rolled dry steel is typically used for sculptures in the art world. Its unfinished surface gives sculptures a different look. This steel is also used for trucks and automobiles that are used for more dirty jobs. A good example of an automobile that hot rolled dry is used for is a dump truck.
Due to its unfinished surface, this steel is more likely to crack when machining it. When hot rolled steel is pickled and oiled it is much easier to machine and less likely to crack. It is possible to machine dry steel, but it is not as easy as finished steel.
The weldability of this type of steel is similar to its machinability. Steel that is not finished is more likely to crack, but the main factor that goes into weldability is carbon content. If the dry steel has a higher carbon content, it is easier to weld.
Hot rolled dry steel can be heat treated depending on the type of steel it is. Certain specifications of steel are more likely to be heat treated than others.

ASTM A-1018 is the standard specification heavy gauge hot rolled steel. This steel is ideal if surface imperfection is not important.
ASTM A-1011 is a standard specification for hot rolled steel. It has great formability and ultra-high strength. This standard is ideal for forming and welding.
CS Type B is a commercial steel with a carbon, phosphorous, manganese, sulphur, and iron chemical makeup.
A36 steel is one of the most common grades of steel used in structural applications. This type covers low-carbon steel.
A572 is the standard specification of high-strength low-alloy structural steel. Grade 42 and 50 A572 steel is best for bolted, riveted, or welded structures.

ANSWER:
The difference between hot rolled and cold rolled steel lies in the extra process that is used to make cold rolled steel. Both cold and hot rolled steel starts off as billets that are then heated to 1700℉ and flattened out with industrial rollers. That steel then cools, shrinks, and then is taken through the cold forming stage where it is stretched out using much more force.
ANSWER:
There are a variety of factors that determine the price of hot rolled coil. The factory prices at steel mills affect the price of hot rolled coil, as well as general supply and demand. When COVID-19 happened, many construction sites were shut down. This meant buildings, typically made with steel, were not being built thus bringing the demand of steel down. This directly changed the price of steel. There are many additional factors that affect these prices.
ANSWER:
Hot rolled steel is steel that has been rolled and flattened out with industrial rollers after being heated to a certain temperature. This steel then cools and shrinks after being rolled out. It undergoes additional finishing processing depending on the type of steel it is.
