Hot-rolled steel plate is a fundamental material in the industrial sector, with applications primarily categorized as follows:
1. Building Structures: Used in bridges, steel structure factories, and high-rise building frames, accounting for approximately 35% (data source: World Steel Association 2023 Report). Its tensile strength typically ranges from 370-500 MPa, allowing it to withstand significant loads.
2. Automotive Manufacturing: Non-exterior components such as body frames and chassis are often made of hot-rolled steel plate, with a thickness range of 1.2-8 mm. Its cost is 20%-30% lower than cold-rolled steel plate.
3. Mechanical Equipment: Construction machinery and agricultural equipment require high-strength components, such as excavator buckets and crane booms.
4. Pipelines and Containers: Oil and natural gas pipelines are often welded from hot-rolled steel plate, requiring high pressure resistance.
