E317-16 Stainless Steel Electrode

EDEN Alloys E317-16/E317L-16 has a nominal composition (wt.-%) of 19.5 Cr, 12.75 Ni, 3.5 Mo, and a maximum carbon content of 0.04. This carbon restriction reduces the possibility of intergranular carbide precipitation and thereby increases the resistance to intergranular corrosion without the use of stabilizers such as niobium or titanium.

The low-carbon alloy however, is not as strong at elevated temperatures as the niobium-stabilized alloys or the standard type 317 weld metal with higher carbon content. EDEN Alloys E317-16/E317L-16 is usually used for welding alloys of similar composition and are utilized in severely corrosive environments (such as those containing halogens) where crevice and pitting corrosion are of concern, such as food processing plants, paper industries, chemical processing facilities, and marine applications.

Application

EDEN E317-16 used for welding of dissimilar steels to carbon steel, or stainless steel to carbon steel. Stringer bead technique should be used for flat, horizontal and overhead welding, weaving technique for vertical position.

E317L-16 Stainless Steel Electrode

EDEN E317L-16 produces a weld deposit similar to that of type 317 stainless steel, except the carbon is limited to a maximum of 0.04%.  In addition to the resistance to pitting and crevice corrosion, this welding electrode offers good resistance to intergranular corrosion as well.

317 electrodes have a greater molybdenum content than USA 316. The increased molybdenum content results in a weld deposit with higher tensile strength at elevated temperatures, stronger resistance against pitting corrosion, and virtually immune from cracking as the deposit cools down from the molten stage. USA 317 weld deposits exhibit smooth bead appearance and easy slag removability. This electrode is typically used where strong corrosion resistance against sulfuric or sulfurous acids is required such as in the chemical, paper and textile industries.

APPLICATIONS:

Welding of AlSl317, AlSl317l stainless steel.

DESCRIPTION:

EDEN 317L is a lime-titania type stainless steel electrode which gives an extra low carbon 18%Cr-12%Ni3%Mo austenitic stainless weld metal. As its molybdenum content is higher than that of NSS-316L, its weld metal has excellent resistance to non-oxidizing acid such as dilute sulfuric acid, and is resistant for inter-cystalline corrosion.

NOTES ON USAGE:

• Keep the arc length as short as possible.
• Dry the electrode at 300 – 350°C for 30 – 60 minutes before use.
• Clean weld area in order to prevent from decreasing corrosion resistance by blending carbon to weld metal.
