Jinyuan provides in-house Electropolishing & Passivation services for various applications in the semiconductor and medical industries. We have solutions that can handle standard grade (304, 316) stainless steel. Our staff is highly skilled and experienced in providing stainless steel solutions. They have the necessary training and expertise to give a fantastic result.
All stainless steels are iron-based alloys with a minimum chromium content of 10.5%. The chromium amount contributes to the basic corrosion resistance of stainless steel. The chromium spontaneously forms a passive oxide layer when exposed to oxygen. This passive oxide layer is very thin but prevents additional oxygen diffusion into the base material and prevents corrosion. Electropolishing in stainless steel enhances the passive oxide layer by making it thicker and thus more resistant to harsh environments.
Enhancing corrosion resistance is not the only benefit when electropolishing stainless steel. Below are a few other benefits:
Every step of our process has been meticulously designed to achieve the highest quality results for our clients from start to finish: our rinsing process is another critical differentiator for our semiconductor industry clients. Achieving a consistent rinse is key to attaining ultraclean results. Our processes include deionized (DI) water, multiple rinsing, ultrasonic rinsing when necessary, and centrifugal drying to ensure that parts emerge from our processes with an ultrasmooth, ultraclean, and defect contaminant-free surface. Our work adheres to semiconductor-specific industry standards (SEMI F19-0185) and general industry standards commonly used like ASTM B912.
