About ER 385 (904L)

ER385 (904L) is a high-alloy, "super austenitic" stainless steel filler metal (wire/rod) known for excellent corrosion resistance, especially in sulfuric, phosphoric, and acetic acid environments, and chloride-containing media, used for welding similar 904L/317L materials in chemical, pharmaceutical, and paper industries, offering superior pitting/crevice resistance and low hot cracking due to low C, Si, S, P, and added Cu/Mo. 
Key Characteristics:
  • Composition: High Nickel (Ni) and Molybdenum (Mo), plus Copper (Cu).
  • Microstructure: Fully austenitic, ferrite-free, reducing sigma phase precipitation.
  • Corrosion Resistance: Excellent against general, pitting, crevice corrosion, and stress corrosion cracking (SCC).
  • Weldability: Low residual elements (C, Si, P, S) reduce hot cracking and fissuring.
  • Applications: Chemical processing (sulfuric/phosphoric acid), fertilizer, paper (pulping), hydrometallurgy, seawater systems, and cryogenic applications. 
Benefits:
  • Superior to standard 316/317L grades in aggressive media.
  • Good low-temperature impact strength (cryogenic). 
Where it's Used (Industries):
  • Chemical & Petrochemical
  • Pharmaceutical
  • Pulp & Paper
  • Fertilizer Production 
In summary: ER385 (904L) is a premium filler metal for demanding corrosive environments where standard stainless steels fail, providing robust protection and weld integrity.
