Stainless Steel Electrodes

SUPERLINK-410

Name: SUPERLINK-410
Brand: DEPL

AWS A5.4: E410-16 EN ISO 3581-A: E 13 R 12

A rutile-coated (lime-rutile, -16 type) austenitic stainless steel electrode. E410-16 type. Produces a smooth, stable arc, fine rippled bead with low spatter, and self-releasing slag. Easy arc striking and re-striking. Easy to use in all positions. Suitable for DC+ (DCEP) power sources; AC machines with sufficient OCV may also be used. Use short arc length and low current to minimise heat input and distortion.

Welding procedure & parameters

DC+ (DCEP) preferred. All positions. Clean all contaminants with SS wire brush and acetone. Keep arc length short. Use stringer beads in flat/horizontal positions; weave in vertical (max 3× electrode diameter). Interpass temp: ≤150°C. Current: 2.5mm: 55–75A; 3.15mm: 70–100A; 4.0mm: 100–130A.

Typical applications

Welding 12Cr martensitic stainless (AISI 410, 403, 405). Steam turbine blades, pump shafts, compressor parts, valve components, petroleum refinery equipment operating in mild corrosion/erosion service. Weld in all positions with short arc length and intermittent passes to control distortion.

Storage & handling notes

Re-dry at 200°C–250°C/1–2 hrs if moisture is suspected. Do not use carbon steel wire brushes on SS welds. Avoid excessive heat input to maintain corrosion resistance. For 308L, 309L, 316L grades: low carbon content is critical — do not over-bake electrodes.
