- Bar
- Wire
- Sheet
- Plate
- Forgings
- Pipe fittings
- Flanges
- Seamless & Welded pipe
- Seamless Tube & Welded tube

About 316l stainless steel pipe
| Parameter | 316 (ASTM A312) | 316L (ASTM A312) | Practical impact |
|---|---|---|---|
| Carbon (max) | 0.08% | 0.03% | Determines sensitization risk at welds |
| Molybdenum | 2.00–3.00% | 2.00–3.00% | Same range - Mo content alone won't tell grades apart |
| Nickel | 10.0–14.0% | 10.0–14.0% | Identical |
| Tensile strength (min) | 515 MPa | 485 MPa | 316L is slightly lower - matters for pressure rating at ambient temperature |
| Yield strength (min) | 205 MPa | 170 MPa | Relevant for schedule selection under pressure |
| Hardness (typical) | 95 HRB max | 95 HRB max | No practical difference for piping |
316L performs well in
- Dilute chloride solutions at moderate temperatures (roughly below 60°C)
- Acidic process streams - sulfuric acid concentrations up to about 10%, phosphoric acid, many organic acids
- Seawater cooling loops where flow velocity is maintained and stagnation avoided
- Pharmaceutical and food-grade hygienic piping where surface finish and cleanability matter
- Urea and fertilizer plant applications, common in the Middle East and North Africa
- Cryogenic service down to -196°C - 316L retains toughness at liquid nitrogen temperatures, which is why it appears in LNG regasification terminals
Selection Guide: Seamless vs. Welded
Choosing the right 316L pipe depends on your pressure requirements:
Seamless 316L: Best for high-pressure systems (Oil & Gas, Nuclear). It offers uniform strength as it has no longitudinal seam.
Welded 316L: More cost-effective for large-diameter applications (Water treatment, Architectural). Modern laser-welding techniques make the "seam" nearly as strong as the parent metal.
