Influence of blackening treatment of 45 ° steel on accuracy

Contact machining for many years, equipment accessories 45 # steel surface treatment, whether there is an impact on the dimensional accuracy of parts? 45 ᦇ blackening of steel has no effect on the dimensional accuracy, because blackening is a common means of chemical surface treatment. The principle is to produce an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. In the surface treatment, the dimension will not deform, so it will not affect the accuracy of parts.

In the process of machining, the parts with low appearance requirements need surface treatment, which can be blackened. In the machining industry, the surface blackening treatment of 45 ° steel parts is also called bluing. If the machining dimension of precision mechanical parts has accuracy requirements, different surface treatment processes can be selected according to the purpose of parts design. In the surface treatment process, 45 ° steel has blackening, chromium plating, nickel plating, zinc plating and other treatment. If the processing accuracy requirements on the production drawings are different, the reasonable surface treatment process should be selected.
