OK Autrod 13.40

OK Autrod 13.40 is a Ni‑, Mo‑alloyed, copper‑coated wire designed for Submerged Arc Welding (SAW) and is typically used with OK Flux 10.62. It delivers high strength and toughness for high‑strength steels up to 550 MPa (620 MPa in AC) and low‑temperature applications.

Key Features

• Consistently high‑quality SAW wire with tight chemistry tolerances
• Low‑friction spools and easy decoiling for defect‑free operation
• Copper coating and controlled helix for excellent conductivity and stable wire feed
• EcoCoil 1000 kg packaging for high‑productivity, crane‑handled, partially unwrapped coils
• Compatible with ESAB’s meticulously manufactured SAW fluxes (BlockPac, buckets, BigBag)
