Description: AFM ER385 is used primarily for welding of ASTM B625, B673, B674, and B677 (UNS
N08904) materials for the handling of sulfuric acid and many chloride containing
media. It may also be used to join Type 317L material where improved corrosion
resistance in specific media is needed. AFM ER385 may be used for joining UNS
N08904 base metals to other grades of stain-less steel. The elements C, S, P,
and Si are specified at lower maximum levels to minimize weld metal hot
cracking, and fissuring (while maintaining corrosion resistance) frequently
encountered in fully austenitic weld metals.
