High-speed tool steel is also an alloy tool steel, which contains C, Mn, Si, Cr, V, W, Mo, Co. And it can be used to make high-speed rotary cutting tools, wear-resistant, high temperature resistant, which is Cr, V, W, Mo have a relatively large proportion (you are also peers, I won’t go into details here), take W12Cr4V5Co5 as an example, Cr->3.
High-speed tool steel is also an alloy tool steel, which contains C, Mn, Si, Cr, V, W, Mo, Co. And it can be used to make high-speed rotary cutting tools, wear-resistant, high temperature resistant, which is Cr, V, W, Mo are relatively large (you are also peers, I won’t go into details here). Take W12Cr4V5Co5 as an example, Cr->3.75%-5%, V->4.5%-5.25%, W->11.75% -13%. Among them, the ratio of Cr and V must not be less than 3%. The content of P and S shall not be greater than 0.030%.

The processing method of alloy tool steel is mainly pressure processing steel and cutting tool steel. There are many types of alloy tool steel, including cold work, hot work, non-magnetic, plastic mold steel, etc. At the same time, the ratio of Cr and V must not be too low. Selection of tool steel for cold work die

The choice of tool steel for cold work molds is based on the main failure mechanism of the mold in practical use. It is not enough to choose tool steel to have only the knowledge of steel performance. It must also consider the number of parts produced, the type of material being processed, the thickness and its hardness. A basic method of selecting tool steel is to first eliminate all the failure mechanisms except wear, and then select the tool steel with the most suitable wear resistance to meet the requirements of product production.
