About ER 385 (904L)

ER 385 (904L) is a high-alloy, super-austenitic stainless steel filler metal used for welding similar base metals, offering excellent resistance to pitting, crevice, and stress corrosion cracking, especially in aggressive media like sulfuric and acetic acids, thanks to its high nickel, chromium, molybdenum, and copper content, plus controlled low carbon, silicon, and sulfur for reduced hot cracking. It's ideal for chemical, pharmaceutical, and fertilizer industries, providing a ferrite-free weld with good cryogenic toughness for joining 904L, 317L, 304, or 316 steels. 
Key Characteristics
  • Alloy Type: Super Austenitic Stainless Steel.
  • Composition: High in Ni, Cr, Mo, and Cu, with controlled low levels of C, Si, P, S to prevent hot cracking.
  • Corrosion Resistance: Superior resistance to general, pitting, crevice, and stress corrosion cracking, particularly in acidic chloride environments.
  • Microstructure: Fully austenitic, avoiding ferrite and sigma phase issues.
  • Mechanical Properties: Good impact strength at low temperatures. 
Primary Applications
  • Welding equipment for handling sulfuric acid, acetic acid, and chloride-containing media.
  • Chemical, pharmaceutical, and fertilizer processing plants.
  • Hydrometallurgy and paper industry equipment.
  • Joining 904L to 304, 316, or 317L where enhanced corrosion resistance is needed. 
AWS Classification
  • AWS A5.9 ER385 (for wire). 
Benefits
  • Excellent weldability with low hot cracking/fissuring propensity.
  • Better performance than standard 316/317L in severe corrosive conditions.
  • Suitable for cryogenic and non-magnetic applications.
