201 Stainless Steel Pipe
201 stainless steel is an austenitic chromium-manganese stainless steel grade. Its typical chemical composition includes 16.0–18.0% chromium (Cr), 3.5–7.5% manganese (Mn), ≤ 4.5% nickel (Ni), and ≤ 0.15% carbon (C). By partially replacing nickel with manganese, 201 stainless steel provides a cost-effective alternative to 304 stainless steel while maintaining good strength and formability.
Compared with higher-nickel austenitic grades, 201 stainless steel pipe offers higher yield strength, good cold-working performance, and acceptable corrosion resistance in indoor, dry, or mildly corrosive environments. It is widely used in applications where appearance, strength, and cost efficiency are prioritized over high corrosion resistance.

|---|---|---|---|---|---|---|---|
| 201 | ≤0.15 | ≤1.00 | 3.5–7.5 | ≤0.060 | ≤0.030 | 16.0–18.0 | ≤4.5 |
Mechanical Properties (Typical)
| Property | Value |
|---|---|
| Tensile Strength | ≥ 520 MPa |
| Yield Strength | ≥ 275 MPa |
| Elongation | ≥ 40% |
| Hardness | ≤ 217 HB |
Heat Treatment of 201 Stainless Steel Pipe / Tube
1. Annealing
Temperature range: 1010–1065 °C
Process: Heating followed by rapid cooling (water quenching or air cooling, depending on thickness)
Purpose:
Relieves stresses caused by cold forming and welding, restores austenitic structure, and improves ductility and corrosion resistance.
2. Stress Relieving
Applied after cold working or welding, especially for precision pipes.
Helps reduce residual stress and improves dimensional stability during fabrication and service.
3. Hardening
201 stainless steel cannot be hardened by conventional heat treatment.
Mechanical properties are mainly determined by chemical composition and cold working, not by heat treatment.
4. Performance Stability
Proper solution annealing stabilizes the austenitic microstructure, improves formability, and enhances performance consistency, especially in welded areas.
Ensures reliable performance in decorative, structural, and general fabrication applications.
Note: 201 stainless steel is an austenitic grade and cannot be strengthened by heat treatment. Heat treatment is used for stress relief, structure restoration, and formability improvement rather than strength enhancement.
Features of 201 Stainless Steel Pipe / Tube
Corrosion Resistance:
Moderate resistance to atmospheric corrosion and mild environments. Suitable for indoor and low-corrosion applications, but not recommended for marine or highly corrosive conditions.
Mechanical Properties:
Higher yield strength than 304 stainless steel in cold-worked condition, with good ductility and forming performance.
