- Excellent Weldability: Low carbon content minimizes carbide precipitation, ensuring stronger welds and reduced sensitization.
- Customizable Specifications: Available in seamless, welded, and ERW forms with thicknesses from 0.5mm to 30mm and diameters up to 24 inches.
- Competitive Pricing: Prices range from US $3500-5500 per metric ton (FOB), depending on specifications and order volume.
hemical Composition of 317L Stainless Steel Pipe
The chemical composition of 317L stainless steel pipe is carefully controlled to ensure enhanced corrosion resistance and weldability. Below is the complete composition as per ASTM A240 and EN 10088-2 (maximum percentages unless specified):
|
Element |
C |
Si |
Mn |
P |
S |
Cr |
Ni |
Mo |
N |
Fe |
|---|---|---|---|---|---|---|---|---|---|---|
|
Max % |
0.030 | 0.75 | 2.00 | 0.045 | 0.030 | 18.0-20.0 | 11.0-15.0 | 3.0-4.0 | 0.10 |
Balance |
Note: Iron (Fe) is the balance element, and the higher chromium, nickel, and molybdenum content enhance corrosion resistance in harsh environments, such as sulfuric and acetic acid media.
