Filler Metal SIDER 309L is used for welding similar alloys in wrought and cast form. This wire is also utilized to weld Type 304 and similar base metals, where severe corrosion conditions exist, as well as in dissimilar welds for joining 304 to carbon steel or the clad side of 304 clad steels and for applying stainless steel sheet linings to carbon steel. This wire is used extensively for join Types 304, 347, 321 and 316 and duplex stainless steels to mild and low alloy steels.
This wire can also provide a buffer layer prior to surfacing for 308L for corrosion resistant overlays and is often used for dissimilar welds because of its tolerance for dilution.
The working temperature should not exceed approximately 400°C (750°F).
Available in diam.: 2.0-4.0 mm on spools of 25 kgs.
