What Coatings Do Stainless Steel Plates Have?
Leave a message
Stainless steel plates are widely known for their corrosion resistance and durability-but in many industrial and architectural applications, additional coatings are applied to improve aesthetics, performance, or surface functionality. So, what coatings are commonly used on stainless steel plates? And which one should you choose?
In this article, we break down the most common types of stainless steel plate coatings, their purposes, and typical use cases-helping you make informed purchasing decisions.
Why Coat Stainless Steel Plates?
Although stainless steel is inherently resistant to rust and corrosion, surface coatings can:
Enhance visual appearance (e.g., color, texture, reflectivity)
Provide extra corrosion or chemical resistance
Improve wear and scratch resistance
Enable fingerprint resistance (for appliances or public-use panels)
Adapt stainless steel for decorative or high-temperature applications
PVD coated stainless steel sheet
PVD is a vacuum-based surface coating that deposits a thin film of metal (e.g., titanium, zirconium) onto stainless steel.
Colors: Gold, bronze, black, blue, rose gold, rainbow
Features: High hardness, scratch resistance, color stability
Applications: Elevator panels, architecture, luxury decoration, kitchen appliances
Passivation Coating Stainless Steel Plate
Passivation involves immersing stainless steel in acid (often nitric or citric) to remove surface contaminants and enrich the chromium oxide layer.
Function: Enhances corrosion resistance without changing appearance
Standard: ASTM A967, ASTM A380
Applications: Chemical processing, marine fittings, oil & gas
Protective film
PE (polyethylene) film: thickness 50-200μm, scratch-proof and dust-proof, commonly used for transportation and storage of stainless steel plates
PVC film: strong acid and alkali resistance, suitable for short-term protection of chemical equipment surface Common Grades & Coating Combinations
Common Grades & Coating Combinations
304 stainless steel + PVD coating → architectural panels
316L + electropolished → pharma/biotech equipment
430 + AFP coating → home appliances
