2B Finish Brushed 410 Stainless Sheet Welding 3048mm 201 304 316 430

The production of colored stainless steel sheets via PVD (Physical Vapor Deposition) involves three core stages: pre-treatment, PVD coating deposition, and post-treatment, with strict parameter control throughout.

This stage ensures a clean, smooth surface for coating adhesion.

Cutting & Polishing: Cut stainless steel coils/plates to required dimensions via laser or shearing. Polish with abrasive belts/wheels to achieve finishes like mirror, brushed, or matte, and remove minor scratches.

Cleaning: First, degrease with alkaline/solvent solutions to eliminate oil and fingerprints. Then, pickle with nitric-hydrofluoric acid to remove oxide layers and polishing residues. Finally, rinse with deionized water and dry with hot air/infrared to avoid water spots.

Completed in a high-vacuum chamber to ensure coating quality.

Vacuum Setup: Load dried substrates into the chamber, then pump to 10⁻³–10⁻⁵ Pa (high vacuum). Heat substrates to 150–300°C and use argon ion bombardment for deep cleaning.

Target Sputtering & Reaction: Select targets based on color (e.g., titanium for gold, chromium for silver). Use magnetron sputtering (plasma bombards targets to release atoms) or arc ion plating (electric arc melts targets) to vaporize targets. Introduce reactive gases (nitrogen for nitrides, oxygen for oxides); target atoms react with gases to form colored compound films (e.g., TiN for rose gold) on substrates.

Thickness Control: Monitor via a quartz crystal sensor to keep coating thickness at 0.1–1 μm (too thin = poor fastness; too thick = brittleness).

This stage enhances performance and ensures compliance.

Cooling & Finishing: Cool the chamber to room temperature, release vacuum, and unload. Optionally, lightly polish coated surfaces for better gloss.

Quality Checks: Test coating hardness (≥2000 HV via Vickers tester) and adhesion (no peeling via cross-cut tester). Use a spectrophotometer to verify color consistency (ΔE ≤ 1 vs. standards).

Packaging: Wrap qualified sheets in anti-scratch film, then pack in cartons/wooden pallets for transport.

Exceptional Material Composition and Corrosion Resistance

​
The CROSS-GRAIN YELLOW BRONZE NANO-COLOR OIL PLATE, available in premium grades 201, 304, 316, and 430, combines the aesthetic appeal of yellow bronze with cutting-edge nano-color oil coating technology. Grades 304 and 316, renowned for their superior corrosion resistance, are ideal for harsh environments, including marine and chemical industries. Grade 304 offers robust protection against oxidizing acids and alkalis, while grade 316 incorporates molybdenum for enhanced resistance to chloride-induced corrosion. Grade 430, with its high chromium content (11.5–14%), provides excellent atmospheric corrosion resistance and thermal stability, suitable for high-temperature applications up to 650°C. The nano-color oil layer further seals the surface, preventing rust and wear, ensuring longevity even in demanding industrial settings. This material is a versatile choice for applications requiring both durability and visual impact.

​Advanced Surface Treatment and Aesthetic Versatility

​
The nano-color oil coating on the CROSS-GRAIN YELLOW BRONZE NANO-COLOR OIL PLATE delivers a vibrant, scratch-resistant finish that resists fading and maintains its luster over time. This treatment not only enhances the bronze’s natural golden-yellow hue but also adds a protective barrier against UV rays, pollutants, and mechanical abrasion. The oil plate’s cross-grain texture ensures improved adhesion of the coating, reducing peeling risks and ensuring uniform color distribution. Available in multiple finishes, including mirror, matte, and brushed, it caters to diverse aesthetic preferences in architectural, decorative, and industrial design. The combination of bronze’s timeless elegance and the nano-coating’s durability makes this product a preferred solution for high-end applications, such as façades, signage, and premium machinery components.

Industrial Performance and Cost-Effective Solutions

​
Engineered for high performance, the CROSS-GRAIN YELLOW BRONZE NANO-COLOR OIL PLATE balances strength, corrosion resistance, and cost efficiency. Grades 201 and 430 offer a budget-friendly alternative without compromising essential properties, with 201 suitable for general-purpose use and 430 excelling in oxidation resistance up to 800°C. The material’s machinability and weldability simplify fabrication, reducing production time and costs. Its lightweight yet sturdy nature makes it ideal for applications requiring both structural integrity and ease of handling, such as automotive trims, kitchenware, and electronic enclosures. By integrating advanced material science with practical design, this product meets the stringent demands of modern industries while providing a sustainable, long-lasting solution that minimizes maintenance and replacement expenses.
