Our Finish First methodology enables world class design and manufacturing engineers to approach metal finishing challenges from the beginning, as an advantage in the design and prototyping stage.
Explore finish firstThe semiconductor industry has some of the most demanding surface finish requirements of any industry that uses our services. Due to the corrosive nature of the liquids and gases used in the manufacturing processes, the industry has developed rigid specifications for acceptable finish quality. Able’s processes meet these specifications, including SEMI F19, which defines the wetted surface characterization requirements and finish acceptance criteria for electropolished 316L stainless steel components.
Able Electropolishing works with companies who manufacture components for the semiconductor industry. One of our customers sends a family of custom 316L SS fittings used in the chemical distribution systems of semiconductor manufacturing facilities. The wetted surfaces require a 10 Ra microinch finish, or better, after electropolishing. In addition, the chromium to iron ratio must be a minimum of 1.5:1 and a chromium oxide enrichment of a minimum chromium oxide to iron oxide ratio of 2:1. The results are verified through optical examination, ESCA, Auger and SEM analyses.
Compared to passivation alone, electropolishing is 30 times more effective for improving corrosion resistance. Send your samples for electropolishing and we will evaluate both finish and dimensional changes. If electropolishing is planned during the design stage, the material removal can be factored into your final size specifications.

Precision and reliability are non-negotiable standards in the aerospace industry, where every component must meet strict requirements for performance, durability, and safety.
With the addition of a fourth-generation tabletop Scanning Electron Microscope (SEM), Able’s state-of-the-art suite of analytic tools continues to grow to meet the requirements of high quality finishing for increasingly sophisticated metal parts.
Stainless steel alloys are prized by manufacturers across industries for their durability and corrosion resistance. Unfortunately, when free iron isn’t removed from the surface of stainless steel parts after machining or stamping, the inherent benefits of stainless alloys diminish: contaminated…
Springs may seem like simple components, but their role in countless applications — from medical devices to aerospace— demands perfection. Even the slightest defect in the metal surface can drastically shorten a spring’s lifespan or lead to catastrophic failure in…
