| High Light | 420 Stainless Steel Cold Rolled Sheet ，Stainless Steel Cold Rolled Sheet Precision ，420 SS Sheet Bright Finish | ||
420 cold-rolled stainless steel sheet is a high-carbon martensitic stainless steel produced through precision cold rolling processes. The cold rolling operation imparts superior surface finish, tight dimensional tolerances, and enhanced mechanical properties compared to hot-rolled equivalents.
This grade offers high hardness (after heat treatment), good wear resistance, and moderate corrosion resistance. It is widely used in applications requiring a combination of sharp cutting edges, durability, and a smooth, bright surface.
| Feature | Benefit |
|---|---|
| Precise dimensional accuracy | Tight thickness tolerances (±0.03mm to ±0.05mm) |
| Excellent surface finish | Smooth, bright, or matte finishes (2B, BA, No.4, HL) |
| Improved mechanical properties | Higher strength and uniformity due to work hardening |
| Superior flatness | Suitable for precision stamping and forming |
| Consistent quality | Uniform microstructure and performance across the coil |
| Element | Content Range |
|---|---|
| Carbon (C) | 0.15% – 0.36% |
| Chromium (Cr) | 12.00% – 14.00% |
| Manganese (Mn) | ≤ 1.00% |
| Phosphorus (P) | ≤ 0.040% |
| Sulfur (S) | ≤ 0.030% |
| Silicon (Si) | ≤ 1.00% |
Note: The carbon content allows hardening by heat treatment to achieve HRC 50–55. Chromium provides moderate corrosion resistance.

| Width | 500 mm – 1500 mm (slit or mill edge) |
| Width Tolerance | 0 / +3 mm (slit edge) |
| Length | Coil form: as required (typically 50–500 kg coils) Sheet form: 1000–4000 mm (cut-to-length) |

| Finish Code | Description | Typical Application |
|---|---|---|
| 2B | Smooth, matte grey finish produced by cold rolling, followed by annealing and pickling | General industrial, stamping, forming |
| BA (Bright Annealed) | Mirror-bright, reflective finish obtained by bright annealing in a controlled atmosphere | Decorative household appliances |
| No.4 | Brushed / satin finish (120-320 grit) | Architectural panels, kitchen equipment |
| HL (Hairline) | Long, continuous brush lines | Elevator panels, decorative trim |
| No.8 (Mirror) | Highly reflective mirror finish | Cosmetic packaging, high-end decoration |

| Quenched & Tempered | 800 – 1000 | 600 – 800 | 8 – 12 | HRC 50 – 55 |
Note: Mechanical properties vary with carbon content and heat treatment parameters. Values shown are typical.
| Process | Temperature | Cooling Medium | Resulting Hardness |
|---|---|---|---|
| Annealing | 750 – 800°C | Furnace slow cool | ≤ HB 235 |
| Hardening | 980 – 1040°C | Oil or air | HRC 50+ |
