According to the type and accuracy requirements of the measuring tool, different steel grades can be selected for the measuring tool:
According to the type and accuracy requirements of the measuring tool, different steel grades can be selected for the measuring tool:
(1A measuring tool with simple shape and low precision requirements
Carbon tool steel is available. Such asT10A,TIIA,T12A. Due to the low hardenability of carbon tool steel, the use of water quenching for large measuring tools will cause large deformation. Therefore, this kind of steel can only manufacture calipers, templates, gauges and other measuring tools with small size, simple shape and low precision requirements.
(2Measuring tools with higher precision requirements
(Such as block gauge, plug gauge material)High carbon and low alloy tool steels are usually selected. Such asCr2,CrMn,CrWMnAnd bearing steelGCr15Let's wait. Because this kind of steel is added in high carbon steelCr,Mn,WIt can improve the hardenability, reduce the quenching deformation, improve the wear resistance and dimensional stability of the steel.
(3A measuring tool with simple shape and low precision that makes it vulnerable to impact in the rain
Such as simple flat template, caliper, ruler and large measuring tools, carburized steel can be used15.20,15Cr,20CLet's wait. However, the measuring tool must be used after carburizing, quenching and low temperature tempering. After the above treatment, the surface has high hardness, high wear resistance, and the heart maintains enough toughness. Medium carbon steel can also be used50,55,60,65Manufacturing measuring tools, but after tempering treatment, and then after high-frequency quenching and tempering use, can also ensure the accuracy of measuring tools.
(4Stainless steel can be selected for measuring tools working under corrosive conditions4Cr13,9Cr18manufacture
After quenching, tempering treatment can make its hardness up toHRC56one58At the same time, it can ensure that the measuring tool has good corrosion resistance and sufficient wear resistance.
As a precision parts size pneumatic measurement equipment manufacturer, we have19+Years design experience engineer, can provide a variety of measurement solutions. The pneumatic probe produced by the use of German imported steel, to ensure the real material, after the original 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.
