Stainless steel is a steel made of chromium, which has the ability to resist discoloration and rust prevention.
Rolling is a metal forming process in which metal materials reduce the thickness by one or more pairs of rollers.
It also makes the thickness of the whole material uniform, just like the dough.
Stainless steel rolled steel plate is a kind of steel product rolled into steel plate under various conditions.
Stainless steel cold rolled steel plate and hot rolled steel plate are two types of rolling process.
Rolling is the form of the metal rolling at the rising temperature.
If the temperature of the metal is higher than its re-crystal temperature, the process is called hot rolling.
If the temperature of the metal is lower than its re-crystal temperature, the process is called cold rolling.
Stainless steel hot rolled sheet: Hot Rolled is the process of rolling steel at a high temperature of about 1700 degrees Fahrenheit or above.
It is higher than the re-crystalline temperature of the steel, so it is called hot rolled steel plate.
It is easy to form when the steel is above the re-crystalline temperature.
In this process, it is easy to make steel of larger size.
Hot rolled steel products such as hot rolled steel bars are used in the welding and construction industries to manufacture rail tracks and I-
Beams, these are used in cases where precise shapes and tolerances are not required.
Stainless steel cold-rolled steel plate: cold-rolled steel plate is processed by further processing of hot-rolled steel plate.
This is handled in cold reduction mills where the material is cooled at room temperature.
Next, it will go through the rolling process of annealing or temperature adjustment.
This will produce steel with closer dimensional tolerances and a wider range of surface finish.
This process brings a higher yield point advantage, such as: in terms of usage and volume, the hot rolling process is more than any other manufacturing process, in all cold processing processes, the tonnage of cold rolling process is the most.
The roller holder combines the roller pairs together to make the rolling mill, which can quickly process the metal into products such as steel.
Beam, corner material, channel material, Rod material and guide rail.
Most steel mills have rolling mill departments that can convert casting products into finished products.
Hot rolled steel plates of thick or thin stainless steel can handle high temperature.
Hot-rolled steel is usually cheaper than cold-rolled steel because it usually has no delay in the production process, while cold-rolled steel plates need to be reheated.
On the other hand, stainless steel cold-rolled steel plates increase yield and tensile strength, thus producing cold-rolled finished rods that are more difficult to process than hot rolling.
