Techalloy 385 description: Techalloy 385 is used for welding materials of similar chemical composition which are used for fabrication of equipment and vessels for the handling of sulfuric acid and other media containing chloride. 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.
