VT machining provides precision chemical etching of stainless steel for customers who need burr-free, stress-free thin-metal parts made to an exact drawing. Stainless Steel is corrosion resistant, strong and hygienic (304/316 grades), and photochemical etching lets us reproduce fine features in it without the mechanical force, tooling cost or edge stress of stamping or laser cutting.
Why Chemically Etch Stainless Steel?
Photochemical machining removes stainless steel by dissolving it through a patterned photoresist, so there is no contact force on the part. The result is completely flat, burr-free and free of the work-hardening and heat-affected zones that mechanical and thermal methods introduce. Because stainless steel is corrosion resistant, strong and hygienic (304/316 grades), etching is often the only way to hold very fine apertures and intricate profiles in it economically.
Stainless Steel Etching Capability
- Foil thickness typically 0.02–1.0 mm
- Minimum feature size around 0.8 × the metal thickness
- Burr-free, stress-free, perfectly flat parts
- Tooling-free — designs are revised in artwork, so prototypes are fast
- High repeatability from the same digital master across volume runs
Typical Applications
Stainless steel is the workhorse of precision etching across most industries. Common etched stainless steel parts include filtration meshes, flat springs, shims, encoder discs and surgical components. Each is produced to your CAD or 2D drawing, with the open area, pitch and overall geometry made to order.
From Drawing to Delivered Stainless Steel Parts
Send us your artwork, the stainless steel grade and thickness you need, and your quantity. We confirm feasibility, suggest the optimal foil and finish, prototype quickly and then scale to production from the same master. Post-etch finishing such as plating or passivation can be arranged where your application requires it.

Frequently Asked Questions
Why choose chemical etching for Chemical Etching Stainless Steel?
Chemical Etching Stainless Steel needs no hard tooling, so designs can be revised quickly and produced flat, stress-free and burr-free — ideal for fine-pitch, thin-gauge precision parts.
What materials can be chemically etched for Chemical Etching Stainless Steel?
For Chemical Etching Stainless Steel we etch aluminum, stainless steel, titanium, nickel, copper, brass, steel, silver, molybdenum, tungsten and invar. Material choice follows your corrosion, precision and application needs.
How fine and burr-free is Chemical Etching Stainless Steel?
Because chemical etching removes metal without mechanical force, Chemical Etching Stainless Steel is completely burr-free and stress-free, holding very fine features and apertures that mechanical methods cannot.
