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, makes stainless steel etching at Advanced Chemical Etching one of our most popular manufacuring processes, 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 when etching stainless steel

As well as our innovative stainless steel etching process, ACE can also offer a number of  added-value processes such as forming, machining and wire eroding, meaning that complex 3D metal parts can be manufactured completely in-house, from formed busbars through to folded shielding components. 

Metal Grades For Stainless Steel Etching

  • Austenitic 300 series
  • Ferritic/martensitic 400 series
  • Precipitation hardened (17-4, 17-7)
  • Sandvik Chromflex (7C27Mo2, 13C26, 12C27, 6C27), Hiflex
  • Uddeholm strip flapper valve steel (20C, 716)
  • Electrical Steel Transil, Scotsil (uncoated)
  • High carbon steels (all grades and hardness)

  • Did You Know?

    Advanced Chemical Etching specialises in the manufacturing of precision etched stainless steel components for customers in more than 15 sectors.

  • Etching Stainless Steel – A Flexible Process

    Importantly, as the temper or hardness of the material doesn’t affect our stainless steel etching process, we are able to chemical etch stainless steel in the annealed condition or very hard grades.
