Carbon Steel Hot-Rolled Steel Plates

• Composition: Carbon steel hot-rolled steel plates mainly consist of iron and carbon, with carbon content generally ranging from 0.05% to 2.11%. Besides, they may also contain small amounts of other elements such as manganese, silicon, sulfur, and phosphorus.
• Production Process: They are produced through the hot rolling process. In this process, the steel billet is heated to a high temperature, usually above 1000°C, and then passed through a series of rolling mills to be rolled into plates of different thicknesses and widths.
• Properties:
  • Good Formability: They have relatively good plasticity and toughness, which makes them easy to be formed into various shapes through processes such as bending, stamping, and welding, meeting the needs of different manufacturing processes.
  • Moderate Strength: The strength of carbon steel hot-rolled steel plates can be adjusted by controlling the carbon content and heat treatment process. Generally, they have moderate strength and can meet the requirements of general engineering structures and mechanical parts.
  • Economical Efficiency: Carbon steel plate is relatively inexpensive compared to some alloy steels, making carbon steel hot-rolled steel plates a cost-effective material choice for many applications.
• Applications: They are widely used in construction, machinery manufacturing, automotive industry, and other fields. In construction, they are used for building structures, such as beams, columns, and steel plates for bridges. In the machinery manufacturing industry, they are used to manufacture various mechanical parts, such as gears, shafts, and brackets. In the automotive industry, they are used for manufacturing car bodies, chassis, and other components.

Alloy Steel Hot-Rolled Steel Plates

• Composition: Alloy steel hot-rolled steel plates are based on carbon steel, with the addition of one or more alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), vanadium (V), and titanium (Ti). The total content of alloying elements is usually between 5% and 10%.
• Production Process: Similar to carbon steel hot-rolled steel plates, alloy steel hot-rolled steel plates are also produced through the hot rolling process. However, due to the presence of alloying elements, the production process may require more precise control of temperature, rolling speed, and other parameters.
• Properties:
  • High Strength and Toughness: The addition of alloying elements can significantly improve the strength and toughness of steel plates. They can withstand higher loads and impacts, making them suitable for applications in harsh working conditions.
  • Good Wear Resistance and Corrosion Resistance: Some alloying elements, such as chromium and nickel, can enhance the wear resistance and corrosion resistance of steel plates. This makes alloy steel hot-rolled steel plates have better durability in corrosive environments or under conditions of high friction.
  • Excellent Heat Resistance: Alloy steel hot-rolled steel plates have better heat resistance than carbon steel plates. They can maintain stable mechanical properties at high temperatures, making them suitable for applications in high-temperature environments.
• Applications: They are mainly used in high-end manufacturing and engineering fields that require high-performance materials. For example, in the aerospace industry, they are used to manufacture aircraft structural components, landing gears, and engine parts. In the petrochemical industry, they are used to manufacture reactors, pipelines, and storage tanks that need to withstand high temperatures and pressures. In the power generation industry, they are used for manufacturing turbine blades, boiler tubes, and other components.

According to the document on the imposition of provisional anti-dumping duties issued by the Ministry of Industry and Commerce of Vietnam yesterday, Vietnam has imposed sanctions on China Baosteel Co., Ltd., Anshan Iron and Steel Co., Ltd., Shougang Iron and Steel Co., Ltd., Shagang Iron and Steel Co., Ltd., Hegang Iron and Steel Co., Ltd., Benxi Iron and Steel Co., Ltd., Steel products exported to Vietnam by dozens of steel companies and related trading companies such as Shandong Iron and Steel and Rizhao Steel are subject to different levels of anti-dumping tax rates, namely 19.38%, 26.94% and 27.83%, a total of three levels of anti-dumping tax rates. The anti-dumping duties will be imposed on March 8, 15 days later.

On February 20, 2025, the Trade Committee of the Ministry of Trade, Industry and Energy of South Korea proposed to the Minister of Planning and Finance of South Korea to impose temporary anti-dumping duties of 27.91% to 38.02% on China. According to the preliminary ruling, the dumping tax rates for different companies are 27.91% for Baosteel, 29.62% for Jiangsu Shagang, 38.02% for Xiangtan Iron and Steel, Sano International and Xiamen International Trade Holdings, and 31.69% for other suppliers in China.
