FAQ – Duplex Steel S32205 Seamless Pipe
Q1: Why choose S32205 over S31803 for critical applications?
A1: S32205's tighter chemistry specifications, particularly minimum nitrogen content, ensure more consistent pitting corrosion resistance, mechanical properties, and weldability, reducing application risk in critical services.
Q2: What is the typical Critical Pitting Temperature (CPT)?
A2: S32205 typically exhibits CPT ≥ 35°C (95°F) per ASTM G150, making it suitable for most seawater and chloride applications. Actual values depend on specific heat chemistry and processing.
Q3: Can it be used for subsea applications?
A3: Yes, S32205 is widely used for subsea pipelines, manifolds, and Christmas trees due to its combination of strength, corrosion resistance, and compatibility with cathodic protection systems.
Q4: What post-weld heat treatment is required?
A4: Generally, full solution annealing is not required for thin to medium sections if proper welding procedures are followed. For thick sections (>20mm), stress relief at 1100-1125°F (595-605°C) may be specified by certain codes or for dimensional stability.
