ISO8418 Hot work tool steel is particularly suitable for use in die casting, hot forging, hot extrusion and other industries with high performance requirements. During hot working, this steel can withstand high pressure, high load and high temperature, while maintaining good stability and durability. In addition, it also has good toughness and wear resistance. And it can effectively extend the service life of the mold and improve production efficiency.
In short, it is a high-quality high-performance die steel, widely used in various thermal processing fields. And it provides reliable support and guarantee for industrial production.
Operating Recommendation 1
1. Chemical composition control: According to ISO 8418 standard, select the appropriate chemical composition to ensure that carbon (C), silicon (Si), manganese (Mn), chromium (Cr), molybdenum (Mo) and other elements are within the specified range. Strictly control the content of harmful elements such as sulfur (S) and phosphorus (P) to improve the purity and performance of steel.
2. Smelting and casting: Workers adopt appropriate smelting methods to obtain uniform and clean liquid steel with chemical composition. During the casting process, pay attention to controlling the casting temperature and speed to avoid defects.
3. Forging and rolling: Forging and rolling at the right temperature to obtain the desired shape and size. Control the cooling rate after forging and rolling to avoid excessive internal stress and uneven structure.
4. Heat treatment: According to the heat treatment system recommended by ISO8418 hot work tool steel standard, quenching, tempering and other treatments are carried out to obtain the required hardness, toughness and heat resistance. Control the temperature and time of the heat treatment process to ensure the stability of the treatment effect.
Operating Recommendation 2
5. Processing and surface treatment: After heat treatment, necessary mechanical processing, such as turning, milling, grinding, etc., is carried out to achieve the required surface roughness and dimensional accuracy. According to the need, the surface treatment, such as shot peening, carburizing, nitriding, etc., to improve the wear resistance and corrosion resistance of the surface.
6. Quality inspection and control: chemical composition analysis, mechanical property testing and metallographic observation are carried out according to the standard to ensure product quality meets the standard requirements. Non-destructive testing of products, such as ultrasonic testing, magnetic particle testing, etc., to find potential defects.
7. Use and maintenance: During use, pay attention to avoid overload and overheating, and regularly check and maintain the working state of the tool. If damage or performance degradation is found, timely replacement or repair to ensure production efficiency and product quality.
Applications of ISO8418 Hot Work Tool Steel
1. Forging industry: manufacturing forging dies, such as hammer forging dies, stamping dies, extrusion dies, etc. These molds operate at high temperatures and pressures, requiring the material to have high thermal stability and wear resistance.
2. Hot extrusion and die casting industry: ISO8418 hot work tool steel is very suitable for the manufacture of hot extrusion molds, die casting molds, etc.
3. Hot shear and hot heading industry: In these processes, tools and molds need to withstand shearing or upsetting operations at high temperatures, which requires extremely high thermal stability and wear resistance of materials.
4. Other hot processing fields: In addition to the above fields, this steel can also be used in other hot processing fields. Such as fixtures in heat treatment equipment, stoves, thermocouple protective covers, etc. These parts need to withstand high temperatures and corrosion, and the performance of ISO 8418 makes them an ideal choice.
