hot-rolled steel plate is a fundamental and versatile industrial material, serving as the backbone for construction, manufacturing, and infrastructure projects worldwide. Produced by heating large steel slabs above their recrystallization temperature (typically over 1700°F / 925°C) and then rolling them to a specific thickness, this process results in a robust and economically efficient product.

　　The key characteristic of hot-rolled plate is its exceptional strength and durability. The high-temperature rolling process refines the steel's grain structure, enhancing its mechanical properties to withstand immense stress, heavy loads, and impact. It is commonly available in higher strength grades, including High-Strength Low-Alloy (HSLA) varieties, offering superior performance without significant weight addition.

　　A distinguishing feature is the mill scale—a dark, blue-grey oxide layer that forms on the surface during cooling. This scale provides a degree of natural corrosion resistance during storage and transit. While often removed for final applications requiring painting or welding, it is a hallmark of the hot-rolling process. The final product has slight dimensional tolerances and a non-glossy, slightly rough surface finish, making it ideal for applications where precise aesthetics are secondary to pure structural integrity.

　　Key Advantages:

　　High Strength & Toughness: Excellent load-bearing capacity and impact resistance.

　　Cost-Effective: The efficient production process makes it more affordable than cold-rolled alternatives.

　　Machinability & Weldability: Readily fabricated, cut, drilled, and welded with standard methods.

　　Availability: Offered in a vast range of thicknesses (from 3mm to over 200mm), widths, and grades (e.g., ASTM A36, A572, AR360) to meet diverse specifications.

　　Primary Applications:

　　Hot-rolled steel plate is indispensable in creating structural frameworks for buildings and bridges, manufacturing heavy equipment for agriculture and mining, building ships and barges, constructing pressure vessels and storage tanks, and forming the chassis and components for railroad cars and large machinery.
