Technical data tables
Chemical composition reference — weight %
Alleima rows are nominal compositions, with limits where marked. ATI rows are flat-product chemistry limits, not pipe limits. “—” means no value is provided here; it does not mean zero.

Mechanical property reference
Values apply to the cited mill product and test basis. They are not certificates or universal acceptance values for Tokk Steel material.

| 310S — ATI flat-product reference | 25 | 314 typical | 624 typical | 42.6 typical | Not listed |
310S — ATI flat-product reference: ATI chemistry limits reference ASTM A167/A240 flat products. Mechanical figures are typical sample averages at 25°C with 50.8 mm elongation gauge length. These are not A312 pipe acceptance limits. View source datasheet ↗

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.
| NPS (in.) | OD (mm) | Wall (mm) | ID (mm) | Approx. kg/m |

TP310S / 310S: material identity and selection
310S is identified as UNS S31008 and should be specified separately from 310. Grade-family guidance discusses oxidation behaviour for elevated-temperature applications; the actual service limit remains a design decision.
| Reference item | Technical guidance |
|---|---|
| Grade designation | TP310S / 310S |
| UNS identifier | S31008 |
| Material family | Austenitic chromium-nickel 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
Use ASTM A312 requirements applicable to the selected pipe grade and ordered edition. Do not transfer a temperature value from a sheet or plate datasheet directly to a pipe design.
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.

Send the details below so our team can review your requirement. Sizes, supply conditions and documentation will be confirmed with your quotation.
| Material | Stainless steel |
| Grade | TP310S |
| Manufacturing type | Specify seamless or welded where applicable |
| Dimensions | Provide outside diameter, wall thickness and length |
| Standard & tolerance | Provide the applicable project specification |
| Finish | Specify your required surface finish |
| Quantity & documentation | Specify quantity and any certificate or inspection requirements |
Make the TP310S designation explicit
Write TP310S on the enquiry, drawing and purchase requirement where that is the specified grade. A request that says only “310 stainless steel” leaves the suffix unresolved. Define the material standard alongside the dimensions and explain any service or fabrication conditions your engineering review considers relevant.
Comparing supplier quotations
Check the supplied condition and any supplementary requirements separately from the basic grade designation. Compare quotations on a consistent dimensional and documentation basis.
