The Characteristics of Cold Extrusion of High Carbon High Chromium Alloy Tool Steel
High carbon high chromium alloy tool steel is a kind of high performance steel which is widely used in the production of cutting tools, die and ripper. In the process of producing such steel, cold extrusion process has a very important place. This article will talk about the characteristics of cold extrusion of high carbon high chromium alloy tool steel.
The high carbon high chromium alloy tool steel has a very high wear resistance and high fatigue strength. It can be used to make the tools and dies used in machining and cold stamping. It has a higher hardness, strength and wear resistance than the conventional high speed steel. The alloy steel has excellent mechanical properties, good thermal stability and good oxidation resistance as well.
The cold extrusion process is an effective way to produce such tool steels. It is suitable for manufacturing metric size and complex shape products with high accuracy and precision. The performance of the cold extrusion parts is higher than that of forging, since the cold extrusion is of homogeneous microstructure and uniform chemical composition.
The advantages of cold extrusion of high carbon high chromium alloy tool steel are mainly due to its high yield strength combined with good toughness, wear resistance and fatigue strength. Compared with conventional hot working, cold extrusion process has lower energy consumption, which means the cost of production is lower.
Besides, there is little material waste and low degree of deformation of the material during the cold extrusion process, which can effectively reduce the processing time and improve the production efficiency. In addition, good dimensional accuracy and high surface finish of the finished product can be achieved by cold extrusion.
Furthermore, the cold extrusion process can be used to produce cold working dies of different sizes and shapes with higher rates of precision and accuracy. This means that more complex shapes can be created in less time, which is beneficial for the workplace and environment.
In conclusion, cold extrusion of high carbon high chromium alloy tool steel has many advantages and benefits. It has excellent mechanical properties, good thermal stability and high fatigue and wear resistance. The cold extrusion process is energy efficient and produces less material waste compared with other forming processes. It can also produce highly accurate and precise products with great dimensional accuracy and surface finish.
