Vitenam Popular ST7 HR022 HR004 tungsten carbide cold heading die for M2~M8 screw mold

Principles of material selection for tungsten carbide cold heading molds
1. Mechanical properties: Cold heading dies need to have high hardness and strength to ensure that they can withstand large impacts and pressures during the high-speed cold process. Generally speaking, commonly used materials include alloy steel, high-speed steel, carbide, etc.
2. Wear resistance: The cold heading mold will produce greater friction and wear during use, so it needs to have good wear resistance to extend the service life of the mold. Choose materials with high hardness and good durability, such as high-carbon alloy steel, high-speed steel, etc.
3. Corrosion resistance: The cold heading mold may be exposed to some corrosive media during the cold heading process, so materials with good corrosion resistance need to be selected to prevent the mold from being damaged by corrosion. Alloy steel, stainless steel, etc. have better corrosion resistance.
4. Processing performance: The manufacturing of cold heading dies requires a series of processing techniques, including forging, quenching, grinding, etc. Therefore, materials with good processing properties need to be selected to ensure the accuracy and quality of the molds. Generally speaking, commonly used materials include alloy steel, high-speed steel, etc. that are easy to forge and heat treat.
