201 ERW pipe is a widely used stainless steel pipe known for its excellent formability, attractive appearance, and cost-effective performance. Manufactured using electric resistance welding (ERW) technology, these pipes provide reliable structural strength and smooth surface quality for various industrial and decorative applications.
GF Steel supplies premium 201 ERW pipes to customers worldwide, offering stable quality, flexible specifications, and professional export services.
What Is 201 ERW Pipe?
201 ERW pipe is a stainless steel pipe produced from grade 201 stainless steel using the electric resistance welding process. ERW technology creates a strong welded joint without the need for filler material, ensuring high production efficiency and dimensional accuracy.
Grade 201 stainless steel contains lower nickel content compared with 304 stainless steel, making it a more economical option while still providing good corrosion resistance and mechanical performance.
Chemical Composition of 201 Stainless Steel
| Element | Typical Content (%) |
|---|---|
| Chromium (Cr) | 16.0 – 18.0 |
| Nickel (Ni) | 3.5 – 5.5 |
| Manganese (Mn) | 5.5 – 7.5 |
| Carbon (C) | ≤ 0.15 |
| Silicon (Si) | ≤ 1.0 |
| Nitrogen (N) | ≤ 0.25 |
| Iron (Fe) | Balance |
This composition provides good strength and formability at a competitive cost.
Mechanical Properties
| Property | Typical Value |
|---|---|
| Tensile Strength | ≥ 520 MPa |
| Yield Strength | ≥ 275 MPa |
| Elongation | ≥ 35% |
| Hardness | ≤ 95 HRB |
These properties make 201 ERW pipes suitable for both structural and decorative purposes.
