‌‌Hot-rolled steel plate is a steel plate made by rolling ingots or continuous casting billets through a rolling mill at high temperature. Its thickness is generally above 1.2mm. Hot-rolled steel plate has high plasticity and weldability, but low hardness, and is suitable for the production of general structures and welded structures. ‌

Types and application: 

1. Structural steel

Mainly used in the production of steel structures, bridges, ships, and vehicles.

2. Weathering steel

Adding special elements (P, Cu, C, etc.), it has good corrosion resistance and atmospheric corrosion resistance, and is used in the production of containers, special vehicles, and also in building structures.

3. Automobile structural steel

High-strength steel plates with good stamping and welding properties are used in the production of automobile frame, wheel, etc.

4. Hot-rolled special steel

Carbon steel, alloy steel, and tool steel for general mechanical structures are used in the production of various mechanical parts after heat treatment.

5. Cold-rolled original plate

Used to produce various cold-rolled products, including CR, GI, color-coated plates, etc.

6. Steel plate for steel pipe

It has good processing performance and compressive strength, and is used to produce high-pressure gas pressure vessels with a volume of less than 500L filled with LPG, acetylene gas and various gases.

7. Steel plate for high-pressure container

It has good processing performance and compressive strength, and is used to produce high-pressure gas pressure vessels with a volume of less than 500L filled with LPG, acetylene gas and various gases.

8. Stainless steel plate

Stainless steel has good corrosion resistance and is mainly used in food industry, surgical equipment, aerospace, petroleum, chemical industry and other industries.
