It is suitable for making tool steel for various measuring tools. Measuring tools are measuring tools in mechanical manufacturing, such as block gauge, plug gauge, micrometer, etc. They often contact with the measured workpiece during use and are subject to wear and collision. Therefore, gauge steel is required to have high hardness and wear resistance, high dimensional stability and sufficient toughness. For simple measuring tools, non alloy tool steel such as T10A and T12A can be used. High hardness and high wear resistance can be obtained after quenching and low temperature tempering; In order to ensure dimensional stability of precision measuring tools, low alloy tool steel containing W, Mn and Cr, such as CrWMn, GCrl5, etc., is often required. At the same time, the alloy carbide formed can further improve the wear resistance of steel.
