Calculated pipe weight — 40S examples
Calculated using density 8.00 g/cm³ and nominal dimensions: kg/m = π/4 × (OD² − ID²) × density / 1000. Dimensions are in mm. Actual mass varies with alloy density and tolerances; these are not certified weights.

TP317L / 317L: material identity and selection
317L is identified as UNS S31703. Published 317L alloy references describe a high-molybdenum austenitic material. The required chemistry and mechanical acceptance limits must come from the ordered specification.
| Reference item | Technical guidance |
|---|---|
| Grade designation | TP317L / 317L |
| UNS identifier | S31703 |
| Material family | Low-carbon, molybdenum-bearing austenitic stainless steel |
| Pipe specification to review | ASTM A312, where required by the project |
| Tube specification to review | ASTM A269 or the application-specific tube standard |
How to use this information
Compare proposed alternatives using the approved grade and operating conditions. Supplier-specific nominal compositions are reference values for that product, not guaranteed composition for every 317L pipe.
Reference information explains the material or specification. Confirm actual dimensions, grade compliance, certificates and availability with the quotation. Manufacturer-specific approvals and properties apply to that manufacturer’s product.

| Material | Stainless steel |
| Grade | TP317L |
| Manufacturing type | Specify seamless or welded where applicable |
| Dimensions | Provide outside diameter, wall thickness and length |

Specify TP317L as a pipe enquiry
Use the full ASTM A312 TP317L designation together with the required edition. Add nominal size and schedule or the actual outside diameter and wall thickness used by your design. Define length, end condition and quantity independently so they are not inferred from the grade. Include any supplementary testing or documentation requirements in the same request.
Comparing supplier quotations
A grade-specific enquiry is easier to compare when each quotation identifies the same standard, dimensions and supply condition. Resolve any proposed substitute before placing the order.
