Advantages
Advantage | Details |
Ultra-High Corrosion Resistance | Molybdenum (2.0-3.0%) enhances pitting/crevice corrosion resistance; PREN ~24-28; ideal for chloride & acidic chemical media |
Low Carbon Anti-Intergranular Corrosion | C ≤0.03% minimizes sensitization in weld HAZ; excellent post-weld corrosion resistance |
Seamless Structure Integrity | No welded joints; uniform wall thickness; high pressure resistance; low leakage risk for critical chemical lines |
Excellent Processability | Good weldability, formability, bendability; no post-weld heat treatment required in most cases |
Stable High & Low Temp Performance | Reliable from cryogenic to high-temperature chemical process conditions |
