OK Autrod B2 SC

OK Autrod B2 SC is a Cr‑, Mo‑alloyed, copper‑coated SAW wire designed for high‑toughness, creep‑resistant steels. It offers very low impurity levels and is compatible with OK Flux 10.66 for superior post‑cooling performance.

Key Features

• Copper‑coated wire with controlled helix for consistent electrical conductivity and minimal copper transfer to the weld pool.
• Optimized spooling (EcoCoil 1000 kg) reduces friction and enables easy decoiling without wire breakage.
• Low impurity content (X‑bar max 7) and high toughness (X‑bar max 10) when used with appropriate flux.
• Available in multiple diameters and package sizes (30 kg, 280 kg).
