AWS Class E317/317L (-15, -16, -17)
ASME SFA 5.4
UNS W31710, W31713
WT 317L has a reduced possibility of intergranular carbide precipitation and increased resistance to intergranular corrosion without the use of stabilizers such as niobium or titanium. However, this alloy is not as strong at elevated temperatures as the niobium-stabilized alloys or the standard type 317 weld metal with higher carbon content. This electrode is used for welding alloys of similar composition and are utilized in severely corrosive environments where crevice and pitting corrosion are of concern, such as food processing plants, paper industries, chemical processing facilities, and marine applications.
Tensile Strength: 75,000 psi min.
Elongation: 30% min.
Available in multiple sizes and diameters. Available in -15, -16, and -17 coating.
