Special steel refers to steel with specific chemical composition and physical properties.

Special steel refers to steel with specific chemical composition and physical properties. They are usually used in special industrial fields such as aerospace, automotive manufacturing, energy, etc.

The preparation process of Dalian special steel is more complex than ordinary steel, requiring strict control of alloy element content and smelting parameters. These alloy elements can improve the strength, hardness, corrosion resistance and other properties of steel, making it suitable for various extreme environments and requirements.

The following are several common Dalian special steels:

Stainless steel: Stainless steel is composed of iron, chromium, and other alloy elements, with excellent corrosion resistance and excellent performance in humid or acid alkali environments. It is widely used in fields such as food processing equipment and medical devices.

Tool steel: Tool steel has high hardness, wear resistance and high temperature stability, and is suitable for cutting, cooling molds, machine tool parts and other harsh working conditions.

Bearing steel: Bearing steel is made by simply and uniformly adding various alloy elements to provide good fatigue resistance and wear resistance, and is used for manufacturing high-speed rotating bearings.

High speed steel: High speed steel has excellent wear resistance and high-temperature hardness, suitable for cutting tools, milling cutters, and other situations that require frequent contact with metal.
