E(R)385
Short Description:
ER385 (AWS A5.9, EN ISO 14343‑A S20255CuL) is super‑austenitic stainless steel solid wire for TIG / MIG welding of 904L (UNS N08904). Low‑carbon, high‑molybdenum & copper chemistry delivers fully austenitic weld deposit with excellent resistance to pitting, crevice corrosion and stress‑corrosion cracking in sulfuric acid, phosphoric acid and chloride‑containing environments. Low heat‑input and stringer‑bead welding technique is required to prevent hot cracking. Widely used for chemic...

Application Alloy ER 385 (904L) is used for welding materials of similar chemical composition, which are used for fabrication of equipment and vessels for handling of sulfuric acid and many chloride containing media. This filler metal may also find applications for joining Type 317L material where improved corrosion resistance in specific media is needed. In order to reduce the propensity for fissuring and hot cracking, the low melting constituents such as carbon, silicon and phosphorus are controlled to lower levels in this alloy. |
