Stainless Steel Functional Surface Treatment
Anti-Fingerprint Stainless Steel Finish
Specifications, Supply & Technical Guide
Anti-fingerprint stainless steel finish is a functional surface treatment applied over stainless steel to reduce visible fingerprinting and improve day-to-day cleanability. The treatment is often designed to preserve the original appearance of the underlying stainless surface, so the base finish—such as 2B, bright annealed, brushed, satin, patterned or colored stainless—must be specified together with the anti-fingerprint treatment.
Illustrative Anti-Fingerprint Surface
AFP
Illustrative visual reference only. Actual AFP performance and appearance depend on the coating / treatment system, base finish, film thickness, curing route, handling, viewing conditions and cleaning method. Use real coated samples and test data for production approval.
Finish Definition
What is an anti-fingerprint stainless steel finish?
Anti-fingerprint stainless steel uses a functional surface treatment or thin coating intended to reduce the visual impact of fingerprints, oils and routine touch marks while improving ease of cleaning.
The treatment is generally applied after the underlying stainless surface has already been established. This means a brushed AFP sheet should still look brushed, a mirror AFP surface remains reflective, and a patterned surface still retains its underlying texture.
AFP is not one universal standardized chemistry. Different suppliers may use different clear or near-clear coating systems and curing routes. Do not assume a universal contact angle, film thickness, Ra / Rz, chemical resistance or abrasion performance from the phrase “anti-fingerprint” alone.
Define these points before approving an AFP finish
- Stainless steel grade and product form
- Base finish before the anti-fingerprint treatment
- Approved AFP coating / treatment system
- Fingerprint visibility / cleanability test method if controlled
- Ra / Rz where surface roughness is critical
- Reflectivity / gloss / color tolerance where applicable
- Protective film, defect acceptance and cleaning instructions
Finish Evidence
Technical and application evidence for anti-fingerprint approval
The page keeps the total image count to three. For an AFP page, the technical evidence should prove the real treated surface and its cleanability rather than only showing a generic stainless-steel photograph.
Technical evidence image
Use one combined image showing untreated vs AFP-treated surface under controlled light, a real fingerprint / cleaning comparison, the approved sample and, where required, Ra / Rz, gloss or other project-specific test evidence.
Application image
Use one real appliance, elevator panel, door, control panel or high-touch fabricated component where the AFP-treated stainless surface is visible in the final supplied condition.
Supply Specification
Anti-fingerprint stainless sheet, coil, panel and fabricated-part ordering matrix
Define the grade, base finish, dimensions, treatment system, visible side, cleanability requirement and fabrication sequence together. This table is an RFQ checklist, not live inventory.
Specify grade, thickness, dimensions, base finish, treated side and sample.
Define coating continuity, visible-face requirements and conversion route.
Provide drawings, treated zones, fabrication sequence and final handling requirements.
| Supply Form | Required Order Data | AFP Surface Control | Processing / Delivery Notes |
|---|---|---|---|
| AFP Sheet | Grade, thickness, width, length, quantity, base finish and treated side | Approved sample, cleanability / fingerprint target, Ra/Rz / gloss if required and defect limits | Confirm protective film, interleave and packaging |
| AFP Coil / Panel | Grade, dimensions, quantity and visible-face requirement | Control coating uniformity, base-finish appearance and batch consistency | Confirm slitting / CTL / panel-conversion sequence |
| Cut / Formed Blank | Grade, thickness, blank dimensions, drawing and final visible face | Define whether cutting / forming occurs before or after AFP treatment | Protect treated surfaces from tooling marks and contamination |
| Fabricated Part | Drawing, grade, dimensions, quantity and treated zones | Define weld / bend areas, final coating continuity and visual acceptance | Confirm fabrication and coating sequence before production |
Available AFP systems, compatible base finishes, dimensional range and fabrication capability must be confirmed in the actual quotation.
Finish Selection
Anti-fingerprint vs untreated vs PVD colored vs passivated stainless steel
AFP is an easy-clean / fingerprint-control treatment. It should not be confused with an untreated mill finish, a decorative PVD color coating or chemical passivation.
| Surface Route | Primary Purpose | Appearance Effect | Selection Logic | Specification Note |
|---|---|---|---|---|

Anti-Fingerprint
This Page |
Reduce visible fingerprints / improve cleanability | Usually designed to preserve the base-finish appearance | When high-touch surfaces need easier routine maintenance | Specify treatment system + base finish + test / sample |
| Untreated Stainless | Base mill / mechanical finish only | Native appearance of 2B, BA, brushed, satin, etc. | When no AFP functionality is required | Fingerprints / oils may remain more visually apparent |
| PVD Colored | Decorative metallic color | Changes color while retaining base texture | When decorative metallic color is the primary requirement | AFP functionality must be specified separately if required |
| Passivated | Chemical surface conditioning / corrosion-related treatment | Typically not intended as a fingerprint-control coating | When the applicable passivation requirement is specified | Do not treat passivation as automatic AFP treatment |
Processing Route
Typical production route for anti-fingerprint stainless steel
A repeatable AFP surface depends on a controlled base finish, surface preparation, approved coating / treatment application, cure, inspection and downstream handling.
Confirm Base Finish
Define grade, dimensions, visible side and stainless surface.
Clean & Prepare
Remove oils and contamination before applying the AFP treatment.
Apply AFP Treatment
Apply the approved functional coating / treatment by the specified route.
Cure / Stabilize
Complete the supplier-approved curing or stabilization process.
Inspect & Test
Check visual uniformity, cleanability and project-specific performance evidence.
Protect & Pack
Use compatible protection and avoid contamination during delivery.
Surface Control
Roughness, cleanability, visual tolerance and cleaning guidance
Do not publish invented Ra/Rz, film-thickness, contact-angle, abrasion or cleanability values. Use actual supplier data, test reports and approved samples for any numeric acceptance criterion.
Ra / Rz & Production Route
The underlying stainless finish remains a major driver of roughness. A thin AFP treatment does not create one universal Ra / Rz for all products.
- Ra target: specify if required
- Rz target: specify if required
- Base finish: record exactly
- AFP treatment / cure route: record for repeatability
Fingerprint, Gloss & Defect Acceptance
Performance should be judged using a repeatable method, not only a marketing name. Visual approval should consider the treated surface under realistic lighting.
- Define fingerprint / cleaning evaluation method if controlled
- Define gloss / reflectivity change where critical
- Define color shift if the coating alters tone
- Set streak, coating void, stain, haze and scratch criteria
Grades, Film & Cleaning
The point of AFP treatment is easier routine care, but cleaning chemistry still needs to be compatible with the actual coating system.
- Grade / form: confirm by quotation
- Protective film: confirm adhesive / coating compatibility
- Use soft, non-abrasive cleaning materials
- Avoid uncontrolled solvents, polishing or abrasive pads
Application Guidance

Custom Fabricated Parts
Drawing-controlled parts with specified AFP zones and visual limits.
Standards & Equivalence
How to specify anti-fingerprint stainless steel without ambiguity
AFP is generally a supplier / project-defined functional surface treatment rather than one universal numbered stainless finish. Specify the base material and the anti-fingerprint performance requirements separately.
- Base stainless material standard Specify grade, dimensions, tolerances and the incoming base finish before treatment.
- AFP treatment specification Define the approved supplier coating / treatment, treated side and required functional / visual acceptance.
- Ra / Rz / cleanability requirement Add measurable roughness, cleanability, gloss or other performance criteria only when a test method and acceptance limit are agreed.
- Visual approval Use controlled-light samples to compare treated and untreated surfaces, coating uniformity, fingerprint visibility and cleaning outcome.
Do not specify only “anti-fingerprint”.
The phrase does not define one coating chemistry, one film thickness, one contact angle, one Ra/Rz or one abrasion / chemical-resistance level.
The visible result also depends on the underlying 2B, BA, brushed, satin, patterned or colored finish.
For production approval, identify the supplier AFP system, base finish, test / sample method, cleaning route and defect criteria before full release.
