As an important measuring tool in the machining process, the requirements for steel are very strict, and qualified measuring steel should be below4Point requirements:

    1.Abrasion resistance
    In order to maintain the accuracy of the measuring tool in long-term use, the working face of the measuring tool must have a high degree of wear resistance, therefore, hypereutectoid steel with high quenching hardness and good wear resistance is often considered within the scope of steel selection for measuring tools.
    2.Dimensional stability
    The measuring tool should be able to maintain a small size change during use and storage. Therefore, the amount of residual austenite and the residual stress value should be reduced as much as possible. Generally thought to containCr,W,MnSteel with equal alloying elements has a good effect on reducing aging deformation.
    3.machinability
    Good machinability can ensure the high productivity of heat treatment in mass production and reduce the possibility of damage during grinding after heat treatment. Therefore, the steel with good machinability, uniform material, good organization and appropriate annealing hardness should be selected.
    4.Corrosion resistance
    In order to improve the corrosion resistance of measuring tools to atmosphere and hand sweat, many measuring tools use chrome plating and other surface treatment methods or martensitic stainless steel. For example, some parts of the micrometer are coated with dull chrome; The dial gauge rod is made of stainless steel because the surface treatment cannot guarantee the accuracy of the rack9Cr18; Caliper parts are used3Cr13, or4Cr13Made of stainless steel sheet. In the production of measuring tools, hardenable stainless steel has been increasingly used to ensure corrosion resistance.
    As a precision parts size pneumatic measurement equipment manufacturer, the production of pneumatic measuring tools usedImported steel from GermanyGuarantee the real material, throughRaw salt bath heat treatment, high temperature1500°Quench, wear proof, liquid nitrogen-180°Deep cooling to remove internal stress, prevent deformation, manual grinding, ensure micron accuracy.
