SIDER 385 (904) Stainless Steel GTAW Rods

SIDER 385 (904L) Stainless Steel GTAW rods 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.

Available in rods lg 1000 mm, diam 1, 1.2 1.6, 2.0, 2.4, 3.2, 4.0 mm; in packs of 5 kgs.
