304L stainless steel Properties
(1) Low-Carbon Advantage
Carbon ≤0.03%: Reduces sensitization and eliminates post-weld annealing requirements, minimizing intergranular corrosion risk.
Weldability: Maintains corrosion resistance after welding without heat treatment.
(2) Corrosion Resistance
General Corrosion: Resistant to atmospheric, freshwater, and steam environments.
Acid Resistance: Effective in nitric acid and organic acids (e.g., acetic acid).
Limitations: Less chloride-resistant than 316L (e.g., avoid prolonged exposure to saltwater).
