What is Stainless Steel Etching?
Stainless steel etching is the process of using corrosive chemicals to etch complex shapes from sheets of stainless steel metal. Stainless steel etching is a highly accurate process that produces parts with a high level of complexity with no mechanical stress placed on the material. 
We are a market leader in precision stainless steel etching, chemically etching millions of components each month using a wide variety of different grades, such as the austenitic (300 series) and martensitic (400 series) steels. Advanced Chemical Etching can chemical etch stainless steel in thickness ranges of 0.005mm to 2.0mm, and at higher volumes than other chemical etching companies.   

Corrosion Resistant

Stainless steel is a preferred metal due to its outstanding corrosion and oxidisation resistance which, along with other properties such as excellent formability and capability to withstand cryogenic temperatures, make it one of the most popular metals etched at Advanced Chemical Etching with millions of parts in different thickness, grades, finishes and hardnesses etched each month.


Due to its versatility, stainless steel etching is used in a wide variety of products in many industry sectors. Chemical etching Stainless Steel means that areas of the metal surface can be etched or reduced, with no resulting distortion or warping. Multi complex profile shapes can be etched and the edges will remain burr free. 


Benefits Of The Stainless Steel Etching Process

  • Go-To Process

    Low set-up costs and fast lead times make stainless steel etching a go-to process in batch sizes of one to multiple millions  

  • Low-Cost Tooling

    The tooling for stainless steel etching is digital, low-cost and can be modified quickly

  • Right First Time

    No heat or force is used when chemical etching Stainless Steel, so the mechanical properties of the metal remain unaltered and parts are free from stresses and burrs

  • Any complexity

    Component features are etched at the same time so part/feature complexity is not an issue
