Steel is a material made by pressure processing, with specific shapes, sizes, and properties. It mainly includes profiles, plates, pipes, and metals, which can be divided into two types: cold processing and hot processing according to different processing temperatures. The widespread application of steel benefits from its low price and reliable performance, making it one of the material foundations of modern society. The following are the specific applications of steel in different fields:
1‌. Building materials: Steel plays an important role in construction projects, including but not limited to bridges, building structures, high-rise buildings, industrial plants, etc. For example, H-beams are widely used in various civil and industrial building structures, including factories, civil engineering, bridges, vehicles, ships, and equipment manufacturing.
2‌. Mechanical manufacturing: Steel is also widely used in mechanical manufacturing, including the production of various mechanical parts, seamless steel billets, nuts, pry bars, etc. For example, round steel is mainly used to manufacture mechanical parts or as seamless billets, while square steel is commonly used to manufacture various structures and mechanical parts.
3‌. Pressure vessels and special equipment: Specific types of steel, such as steel plates for pressure vessels, are used to manufacture equipment for petroleum and chemical gas separation and gas storage and transportation. These steels need to have good strength, plasticity, toughness, as well as cold bending and welding performance.
4. Transportation: Steel also has important applications in the field of transportation, including manufacturing ships, vehicles, railways, and highway facilities. For example, large angle steel is widely used in large structural components such as factories, industrial buildings, railways, transportation, bridges, vehicles, and ships.
