Hot rolled steel coil
Hot rolled coils are made of slabs (mainly continuous casting slabs) as raw materials, which are heated and made into strip steel by rough rolling mills and finishing mills. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and then rolled into steel strip coils by coilers.

Mechanical properties
Nominal thickness | Yield Strength(Mpa) | Tensile strength(Mpa) | Elongation A50mm% | 180 degree bending test |
>1.5-2.5 | ≤290 | ≥310 | ≥38 | D=0a |
>2.5-3.0 | ≤290 | ≥300 | ≥38 | D=0a |
>3.0-4.0 | ≤290 | ≥300 | ≥40 | D=1/2a |
Application
Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and forming, and good weldability,
so they are widely used in manufacturing industries such as construction, machinery, boilers, and pressure vessels.
Application range:
(1) Processing into ordinary cold rolling after annealing;
(2) Galvanizing by galvanizing units with annealing pre-treatment devices;
(3) Panels that basically do not require processing.
