Two and a quarter percent chromium and a full percent molybdenum give T22 the creep strength for final superheater and reheater tube, high-temperature headers, and hydrogen service where lower-chrome grades run out of margin.

It is supplied from qualified domestic and international mills, then received, inspected, tested, and released under our ISO 9001:2015 system in Hillsboro, Texas, with a full mill test report. ## What SA213 T22 is T22 is a 2-1/4Cr-1Mo ferritic alloy steel, the highest-strength conventional low-alloy boiler tube before moving to the 9-chrome and stainless grades. It resists oxidation and graphitization to about 1100 degrees F and handles high-temperature hydrogen further along the Nelson curve than T11 or T12. ## Chemical composition | Element | Requirement | | --- | --- | | Carbon | 0.05 to 0.15% | | Manganese | 0.30 to 0.60% | | Silicon | 0.50% max | | Chromium | 1.90 to 2.60% | | Molybdenum | 0.87 to 1.13% | | 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 - Final superheater and reheater tube in utility boilers. - High-temperature headers and steam leads. - HRSG high-pressure superheater modules. - Hydrocracker and hydrotreater heater tubes within Nelson curve limits. - Ammonia and methanol plant exchangers in hydrogen service. ## Beyond T22 When T22 runs out of creep margin, the next steps are T91 modified 9-chrome or the austenitic stainless grades TP304H, TP321H, and TP347H. We supply those too. **What to put in your SA213 T22 RFQ** OD, minimum wall, length, quantity, heat treatment condition, hardness cap, PMI requirement, and the ASME Section or licensor specification governing the job. ### 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)[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)[SA213 T5](https://ameritube.net/products/sa213-t5?hsLang=en) ### Industries [Power Generation](https://ameritube.net/markets/power?hsLang=en) Alloy: SA213 T22 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.
