engineers ask how to choose Haynes 230 for sour gas service, the real question is rarely about brochure-level corrosion resistance. It is about design margin. Is the alloy being selected for a hot, sulfur-bearing gas stream where oxidation and sulfidation dominate, or for a wet H2S environment where sulfide stress cracking, chloride contamination, and fabrication details suddenly control the risk? Haynes 230 can be a very effective alloy in some sour gas systems, but it is not a universal answer. The right decision depends on temperature, water phase stability, sulfur chemistry, stress state, welding condition, and how closely the service envelope approaches NACE requirements.
