Special Steel - Alloy Structural Steel

Special steel refers to steel products that have special physical and chemical properties or special uses due to their special composition, structure, and production process. They belong to a branch of the traditional steel industry. There is a big difference in their usage.

Special steel is added more alloy elements and adopts special production and processing technology in the smelting process. The chemical composition, structure and mechanical properties of special steel are better than ordinary steel. The complexity of its crystal grains is higher than that of ordinary steel, so it can obtain more application fields, so it is widely used in fields such as automobiles, machinery, chemicals, ships, railways, aerospace, national defense and military industries that require high steel quality. In the future, with the development of aerospace, national defense and military industry, and the great development of many emerging industries, the application fields of special steel will continue to expand, and the demand will also increase rapidly.
