1.Hot rolled steel strip is rolled at high temperature and has good ductility.
2.Hot rolled steel strip can have a larger thickness.
3.Hot rolled steel strip has better toughness.
4. Difference between hot rolled and cold rolled steel strip:
Cold-rolled steel strip has low toughness due to a certain degree of work hardening, but it can achieve a good yield ratio, and can be used for cold bending spring pieces and other parts. At the same time, because the yield point is close to the tensile strength, there is no foresight for danger during use, and accidents are easy to occur when the load exceeds the allowable load.
1)The cold plate is cold-rolled and has no scale on its surface and good quality. Hot-rolled steel plates are hot-rolled, with scale on the surface and thickness difference.
2)Hot rolled steel strip has poor toughness and surface smoothness, and its price is lower, while cold rolled steel strip has good extensibility and toughness, but its price is higher.
3)Rolling steel strip is divided into cold rolling and hot rolling, with recrystallization temperature as the distinguishing point.
4)Cold rolling: Cold rolling is generally used to produce strip with high rolling speed. Hot rolled steel strip: hot rolling temperature and forging temperature
5) The surface of hot rolled steel strip without electroplating is dark brown, while that of cold rolled steel strip without electroplating is gray, which can be distinguished from the smoothness of surface after electroplating, and the smoothness of cold rolled steel strip is higher than that of hot rolled steel strip.

Hot rolled steel strip is suitable for manufacturing parts processed by cold forming, General construction of buildings, bridges, ships, vehicles, etc.
