201 Colored Stainless Steel Sheet 1.8mm ASTM A240 Laser Cutting Processing
A 201 colored stainless steel sheet starts with ASTM A240 201 stainless steel as the base material, then receives a durable color finish through PVD (Physical Vapor Deposition) or electrochemical coloring processes.
Grade 201 is an austenitic chromium-nickel-manganese stainless steel developed as a lower-cost alternative to 304. While it offers slightly lower corrosion resistance than 304, it provides excellent formability and strength for interior applications where extreme corrosion exposure is not a concern.
The color finish — available in gold, bronze, black, rose gold, blue, and more — is bonded at the molecular level. It will not peel, flake, or scratch off under normal use.
Best suited for: Interior decorative applications where budget matters and corrosion exposure is mild to moderate.
Not recommended for: Outdoor use, coastal environments, swimming pools, or high-humidity industrial settings.

| Feature | Benefit | |
|---|---|---|
| Lower cost than 304 | Approximately 15-25% less expensive than 304-based colored sheets | |
| Permanent color bond | No peeling, flaking, or scratching off | |
| Good formability | Can be bent, stamped, and deep drawn | |
| Wide color range | Standard and custom colors available | |
| Multiple finishes | No.4 brushed, mirror, hairline, embossed | |
| Lightweight strength | High strength-to-weight ratio |
This is the most common question buyers ask. Here is the direct comparison:
| Feature | 201 Stainless Steel | 304 Stainless Steel |
|---|---|---|
| Nickel content | 3.5 – 5.5% | 8.0 – 10.5% |
| Manganese content | 5.5 – 7.5% | ≤ 2.0% |
| Corrosion resistance | Good for interior use | Excellent for interior and exterior |
| Cost | Lower | Higher |
| Best for | Indoor decorative applications | Indoor + outdoor, harsh environments |
| Magnetic? | Slightly magnetic after cold working | Non-magnetic when annealed |
The bottom line: For indoor walls, elevator interiors, kitchen backsplashes, and furniture trim, 201 colored stainless steel sheet is a smart, cost-effective choice. For outdoor facades, coastal areas, or wet environments — spend the extra money on 304 or 316.
| Color | Common Code | Best Application |

UNS Designation: S20100
Note: PVD or electrochemical coloring does not alter the chemical composition of the base material.
| Property | Requirement |
|---|---|
| Tensile Strength (min) | 515 MPa (75 ksi) |
| Yield Strength 0.2% Offset (min) | 205 MPa (30 ksi) |
