Summary for hard chrome temperature range Discussion
Hard chrome temperature range is the key concern in this thread, where Mike Deye asked what operating temperatures applied hard chrome can handle before it “breaks down.” Anders Sundman replied that hard chrome plating loses about 10% of its hardness at 200 °C, 25% at 300 °C, 40% at 400 °C, and more than 50% at 500 °C, noting that beyond that it is “a long road to melt it.” Guillermo Marrufo added that he does not know what the asker means by breakdown, but cautioned that hard chrome is not considered an excellent choice for high-temperature applications, especially in heavy layers, because its cracked structure can expose the substrate and cause consequences. The practical takeaway is that hard chrome may survive high heat to some extent, but its hardness and suitability decline significantly as temperature rises.
Q. I am looking for some information on operating temperatures that the applied hard chrome is able to handle before braking down. Is there any information on this ? I have been looking at a few places but can’t find them. Thanks for the help !

 | A. Mike, In higher temperature than 400 °C reduces the hardness, with temperatures up to 800 °C will show a hardness around 200-250 Hv. Also the fatigue strength reduces. The deposit goes from grey colour to a green oxide. Regards,

 | Properties of teflon only good for 600 °FQ. I am in need of a tough coating with high lubricity and a temperature range up to 600 °F. nick Kreigh Ed. note: This RFQ is outdated, but technical replies are welcome, and readers are encouraged to post their own RFQs. But no public commercial suggestions please ( huh? why?). A. Hi Nick. As you see, we added your inquiry to a thread about hard chrome plating because it may be the coating you are looking for :-) Regards,
