Passivation

Enhance your metal components' lifespan and corrosion resistance with C&H Machine’s expert passivation services. Adhering to industry standards AMS2700, AMS-QQ-P-35, and MIL-DTL-5002, this treatment removes impurities and forms a protective layer, ensuring your parts stay robust and reliable in the toughest conditions. Interestingly, this is an important process to help keep your stainless stain-less.  Choose C&H Machine for superior metal durability and performance.

Electropolishing

Enhance the surface finish and longevity of your metal components with C&H Machine’s expert electropolishing services. Following stringent standards ES 2-82 and ASTM B912, our electropolishing process smooths and cleans the metal surface by removing a thin layer of material. This technique not only improves the aesthetic appearance but also significantly increases the corrosion resistance and durability of your parts. Choose C&H Machine for electropolishing services that deliver superior surface quality and performance, ensuring your components meet the highest industry standards.
