AWS Class ER385
ASME SFA 5.9
ER385 (904L) is a filler metal that is best used on base metals of similar composition. This alloy is often used in the making of equipment that handles sulfuric acid and other materials containing chloride. ER385 is a good filler metal to join alloy 317L when higher corrosion resistance is needed. This alloy contains low amounts of the elements, carbon, silicon, sulfur and phosphorus to reduce the hot cracking and fissuring. ER385 is often used in the chemical, pharmaceutical, and paper industries.
