What is stainless steel etching?
Stainless steel etching is a subtractive metal machining process which uses etchant chemistry to produce complex, highly accurate metal components. It offers a cost-effective alternative to stamping, punching, laser and waterjet cutting thin gauge steels to 1.5mm thick.
Etching stainless steel?
Low set-up costs and quick lead times make etching economical in batch sizes of one to multiple millions. As a production steel etching specialist, Precision Micro supplies high-tech companies with more than two million steel and stainless steel components each month, making it the largest sheet steel etching company in Europe.
Suitable materials and grades
Precision Micro offers chemical etching of ferritic, austenitic, martensitic, duplex and precipitation hardened stainless steel grades from stock. We also machine specialist stainless steel grades, including Sandvik Chromflex strip steels, and work with customer-supplied steels.

Design optimisation without financial penalty
Etch tooling is digital, low-cost and can be adapted quickly allowing for risk-free design optimisation.
Accurate, complex, burr- and stress-free components
No mechanical force or heat is used when etching stainless steel, meaning material properties and characteristics remain unaltered and parts are free from stresses and burrs.
Complexity without cost
With etching, component features are machined simultaneously allowing for almost limitless part complexity. Stainless steel components can be etched with accuracy to ±0.025mm as standard.
- Safety-critical springs and flexures used in satellites, ABS braking, biosensors and fuel injection can now flex millions of times because chemical etching does not alter fatigue strength, recoil and flatness of spring steel.
- Complex, corrosion-resistant micro-filters used in showerheads and insect meshes can be manufactured in economical production volumes as chemical etching only charges for the first hole.
- Chemical etching does not alter the surface finish of stainless steel and is specified for premium automotive interior trim applications including speaker grilles, tread plates, badges and inlays.
