OK Tubrod 15.27

OK Tubrod 15.27 is a basic gas‑shielded flux‑cored welding wire designed for steels with a minimum yield strength of 690 MPa when used with Ar/CO₂ shielding gas.

Key Features

• Provides flat welds with deep penetration and high deposition rates.
• Low diffusible hydrogen levels (H5) for improved weld quality.
• Suitable for high‑strength low‑alloy steels (HY100) and structural applications.
• Can be up to three times more productive than stick welding.
