Comparable International References
| Reference family | How buyers use it | Quotation note |
|---|---|---|
| ASTM A790 / ASTM A928 | Seamless/straight-seam welded and electric-fusion welded ferritic-austenitic stainless pipe references. | Confirm product form, manufacturing route, heat treatment, corrosion testing, and MTC. |
| UNS S32205 / S31803 / EN 1.4462 | Common 2205 duplex stainless grade family for corrosion-resistant pipe enquiries. | Confirm the exact UNS number; S32205 and S31803 are not identical chemistry bands. |
| ASTM A789 / EN 10216-5 comparison | Tube and European stainless pressure pipe/tube references sometimes used for comparison. | Use only when the buyer orders that product form and standard. |
For corrosion-resistant products, grade references are not direct substitutions. Final selection depends on medium, temperature, chloride/H2S/CO2 exposure, product form, manufacturing route, and project code.
