Technical Dialogue Hub
Q1: How does 316L compare to 2205 Duplex for chloride environments?
A: 316L excels in oxidizing chlorides (e.g., hypochlorite solutions), while 2205 dominates reducing chloride media. Hybrid cladding options available.
Q2: Surface prep for hydrogen service?
A: Specify electropolishing + 300°C vacuum bake to eliminate absorbed H₂ (per ASME BPV Code Case 2938).
Q3: Maximum operating temperature?
A: 870°C intermittent (scaling resistance), 540°C continuous (stress rupture considered).
