Nine percent chromium and one percent molybdenum give T9 the best sulfidation resistance in the conventional ferritic family, plus creep strength for metal temperatures beyond T5. It is the tube for the hottest, sourest sections of refinery heaters.

The high chromium content resists sulfidic and oxidizing attack at radiant-section temperatures, and it handles high-temperature hydrogen further along the Nelson curve than T5 or T22. It should not be confused with T91, the modified 9Cr-1Mo-V grade used for supercritical boilers, which has different chemistry, heat treatment, and welding requirements. ## Chemical composition | Element | Requirement | | --- | --- | | Carbon | 0.15% max | | Manganese | 0.30 to 0.60% | | Silicon | 0.25 to 1.00% | | Chromium | 8.00 to 10.00% | | Molybdenum | 0.90 to 1.10% | | Phosphorus / Sulfur | 0.025% max each | ## Mechanical properties | Property | Minimum | | --- | --- | | Tensile strength | 60,000 psi (415 MPa) | | Yield strength | 30,000 psi (205 MPa) | | Elongation in 2" | 30% | | Hardness | 85 HRB max | ## Where it is used - Radiant section tubes in crude, vacuum, and coker heaters. - Hydrogen reformer and hydrotreater service. - High-temperature sulfur and H2S exchangers. - Superheater and reheater tube in industrial boilers burning high-sulfur fuel. ## One order, the whole ladder Refinery heater retubes rarely need one grade. Ameritube quotes T5, T9, T11, T22, and the stainless grades from a single desk, with matching MTR formats and one inspection release. **What to put in your SA213 T9 RFQ** OD, minimum wall, length, quantity, heat treatment, hardness cap, PMI, and the customer or licensor specification. State whether T9 or T91 is intended, they are not interchangeable. ### Documents - [Ameritube main brochure](https://ameritube.net/hubfs/PDFs/main_brochure.pdf?hsLang=en)PDF - [ISO 9001:2015 certificate](https://ameritube.net/hubfs/PDFs/ISO_CERT.pdf?hsLang=en)PDF ### Related alloys [C44300](https://ameritube.net/products/c44300-admiralty-brass?hsLang=en)[C70600](https://ameritube.net/products/c70600-copper-nickel-90-10?hsLang=en)[C71500](https://ameritube.net/products/c71500-copper-nickel-70-30?hsLang=en)[C72200](https://ameritube.net/products/c72200-copper-nickel-chromium?hsLang=en)[SA179](https://ameritube.net/products/sa-179?hsLang=en)[SA213 T2](https://ameritube.net/products/sa213-t2?hsLang=en) ### Industries [Oil & Gas](https://ameritube.net/markets/oil-gas?hsLang=en)[Power Generation](https://ameritube.net/markets/power?hsLang=en) Alloy: SA213 T9 Alloy Steel Boiler Tube × Copper & Brass (Made in USA) **C12200**DHP Copper **C44300**Admiralty Brass **C70600**Copper Nickel 90/10 **C71500**Copper Nickel 70/30 **C72200**Copper Nickel Chromium Carbon & Alloy Steel **SA179**Seamless Carbon Steel **SA213 T2**Alloy Steel Boiler Tube **SA213 T5**Alloy Steel Boiler Tube **SA213 T9**Alloy Steel Boiler Tube **SA213 T11**Alloy Steel Boiler Tube **SA213 T12**Alloy Steel Boiler Tube **SA213 T22**Alloy Steel Boiler Tube Stainless & Duplex **TP304 / 304L**Stainless Steel **TP316 / 316L**Stainless Steel **TP321 / 321H**Stainless Steel **TP347 / 347H**Stainless Steel **SA268**Ferritic Stainless **SA249**Welded Stainless **SA789 S32205 / S31803**Duplex Stainless Nickel Alloys **Alloy 200**Nickel 200 (N02200) **Alloy 276**C-276 (N10276) **Monel 400**Nickel Copper (N04400) **Monel 405**Free-Machining Nickel Copper (N04405) **Alloy 600**Inconel 600 (N06600) **Alloy 625**Inconel 625 (N06625) **Alloy 800**Incoloy 800 (N08800) **Alloy 825**Incoloy 825 (N08825) Not sure? **Ask us**Describe the service and we will recommend the alloy No match.
