ASTM A268 TP430 / UNS S43000 Ferretic Stainless Steel Seamless Tube Heat Exchanger Tube
ASTM A268 TP430 / UNS S43000 is a ferritic stainless steel seamless tube for heat exchangers, containing 16–18% Cr and very low Ni (≤0.75%). It is fundamentally an economical, high-temperature oxidation-resistant tubing without nickel stabilization.
| Grade (UNS) | Key Feature | When to Consider It | When to Avoid It |
| TP409 (S40900) | Cheap, Ti-stabilized | Low-cost exhaust tubes, mufflers, or dry flue gas < 650°C. | Any pressure part or corrosive condensate. |
| TP430 (S43000) | Base grade, high Cr (16-18%) | Dry hot air/gas up to 870°C, nitric acid service, strong caustic (NaOH). Low-cost, non-welded heat exchanger bundles. | Any welding; any aqueous chlorides; any low temp. |
| TP439 (S43035) | Ti-stabilized (improved weldability) | When welding is required but you still need 430-level oxidation resistance. Used in automotive exhaust heat exchangers and welded recuperators. | Chloride pitting environments (same as 430). |
| TP444 (S44400) | Mo-stabilized (18Cr-2Mo) | Slightly wet environments with mild chlorides (e.g., potable water, low-chloride condensate). Has better pitting resistance than 316L in some cases. | High-chloride seawater or strong reducing acids. |

Application
Refineries / Petrochemical: Air preheater tubes (dry flue gas), reformer outlet pigtails (dry H₂-rich gas).
Power Plants: Boiler air heaters, recuperators in gas turbines.
Chemical Processing: Concentrated sulfuric acid (93-98%) coolers, nitric acid condensers, caustic evaporator tubes (NaOH).
Automotive / Marine: Exhaust gas recirculation (EGR) coolers (where condensate is managed).
