Haynes 230 Pipe
Haynes 230 pipe is a nickel-chromium-tungsten-molybdenum superalloy engineered to deliver exceptional high-temperature strength, oxidation resistance, and long-term thermal stability in extreme environments. Withstanding temperatures up to 2100°F (1149°C), this alloy outperforms conventional stainless steels and many nickel-based alloys, making it ideal for critical applications in aerospace, power generation, and industrial processing.
Properties & Advantages
- Outstanding High-Temperature Strength – Maintains structural integrity at 1200°F (649°C) and above, with superior creep resistance compared to stainless steels.
- Exceptional Oxidation & Nitridation Resistance – Forms a protective oxide layer, preventing degradation in aggressive atmospheres.
- Thermal Stability & Fatigue Resistance – Performs reliably under prolonged thermal cycling without embrittlement.
- Good Fabricability & Weldability – Can be welded without preheating or post-weld heat treatment (interpass temp <100°C).
- Resistance to Carburization & Nitridation – Low carbon absorption (10.3 mg/cm² in carburizing tests at 1090°C) and excellent ammonia resistance.

Applications of Haynes 230 Pipes & Tubes
- Due to its unmatched high-temperature performance, Haynes 230 is widely used in:
- Aerospace & Jet Engines – Combustors, afterburners, exhaust components
- Power Generation – Gas turbine liners, heat exchangers, boiler tubes
- Chemical Processing – Reformer tubes, furnace hardware, pyrolysis systems
- Heat Treatment & Industrial Furnaces – Radiant tubes, muffles, thermocouple protection sheaths
Fabrication & Welding Guidelines
- Welding Methods: Compatible with GTAW (TIG), GMAW (MIG), and SMAW techniques.
- Interpass Temperature: Must be kept below 100°C (212°F) to prevent cracking.
- Cold Forming: Possible but requires annealing for severe deformation.
- Machining: More challenging than stainless steel; carbide tooling is recommended.
