Architectural 316 430 420 Stainless Steel Sheet Black Titanium For Bathroom

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.

The Black Titanium Series Stainless Steel Plate offers a superior fusion of aesthetic appeal and robust performance. Its most striking feature is the permanent, deep black titanium coating, achieved through advanced PVD (Physical Vapor Deposition) or high-temperature immersion processes. This coating is exceptionally resistant to fading, peeling, and chipping, ensuring the elegant, modern finish withstands the test of time and harsh environmental exposure. Beyond its visual impact, the surface provides enhanced resistance to fingerprints and minor scratches, making it ideal for applications where both appearance and durability are critical. This series transforms standard stainless steel into a premium material, offering a sleek, contemporary alternative to traditional finishes.

Beyond its aesthetic superiority, this series leverages the inherent material-specific strengths of the 201, 304, 316, and 430 grades to meet diverse application demands. For general use and interior designs, the 201 and 304 series provide excellent corrosion resistance and formability. The 316 series stands out with its exceptional resistance to chlorides and harsh chemicals, making it the optimal choice for marine environments, coastal architecture, and chemical processing plants. For applications where cost-effectiveness is a priority while still requiring a durable and corrosion-resistant material for indoor settings, the 430 series presents a valuable ferritic option. This range ensures there is a perfect Black Titanium solution for every technical and budgetary requirement.

The functional versatility of the Black Titanium Series is a key advantage, making it suitable for a vast array of industries. It is extensively used in high-end architectural cladding, elevator interiors, and luxury appliance manufacturing, where its sophisticated look enhances product value. Furthermore, its durability makes it perfect for automotive trim, commercial kitchen equipment, and specialized industrial machinery. The plates maintain all the desirable properties of the underlying stainless steel, including strength, ease of fabrication, and hygienic non-porous surfaces, while the black coating adds an extra layer of protection. This combination of stunning design, material excellence, and multi-sector applicability makes the Black Titanium Series an intelligent and premium choice for demanding projects.
