Overview of Carbide Steel

Carbide steel is a special steel with high hardness, high strength and wear resistance. It is made of tungsten steel alloy with high melting point as the main component through specific smelting and processing technology. Carbide steel is often used in the manufacture of mold cutting tools and abrasives, and its excellent performance makes it an indispensable material in many industries.

Characteristics and Application of Carbide Steel

High Hardness and Wear Resistance: The hardness of carbide steel is much higher than that of traditional steel, and it has excellent wear resistance. This makes it widely used in the manufacture of cutting tools working under high load, high speed and high temperature. Carbide steel tools can effectively cut a variety of materials, including metals, plastics and wood.

High Strength and Impact Resistance: Carbide steel has excellent strength and toughness. Its high tensile strength and impact resistance make it perform well in applications such as mold manufacturing and fixtures. Carbide steel products can withstand the challenges of high pressure and complex loads, maintain shape and precision, thereby improving production efficiency.

High temperature resistance: Cemented carbide steel has excellent high temperature resistance. It has a low thermal expansion coefficient and a high melting point, and can maintain hardness and stability under high temperature conditions. Therefore, cemented carbide steel is widely used in fields such as high temperature investment molds and mold heat treatment.

Corrosion resistance: Cemented carbide steel has good corrosion resistance and can resist erosion in environments such as acid, alkali, moisture and oxidation. This makes the use of cemented carbide steel more reliable in special environments and extends its life.

Preparation process of cemented carbide steel

The preparation process of cemented carbide steel depends on the preparation process of tungsten steel alloy. Generally speaking, the main steps in preparing cemented carbide steel include raw material selection, smelting, spray forming and heat treatment.

Raw material selection: The main component of cemented carbide steel is tungsten steel alloy. By selecting the appropriate raw material ratio, the desired chemical composition and properties can be obtained.

Melting: The selected raw materials are melted at high temperature and formed into block-shaped cemented carbide steel through a specific cooling process. In this process, the melting temperature must be controlled, the stability of the chemical composition must be maintained, and undesirable impurities must be eliminated.

Spray forming: The desired shape and size are formed by melting the cemented carbide steel and spraying it onto the mold or workpiece. This forming method can be achieved under high temperature and high pressure to ensure the compactness and precision of the product.

Heat treatment: Through the heat treatment process, cemented carbide steel can obtain the required hardness and strength. Heat treatment includes heating, insulation and cooling steps to adjust the crystal structure and performance of cemented carbide steel.
