Flux Cored Welding Wire for High Tensile Steel – K-71TM

K-71TM is a professional-grade flux cored welding wire for high tensile steel, specially engineered for 490 MPa class materials. It delivers superior arc stability, consistent impact toughness, and clean slag removal for multi-position applications. Whether you’re welding offshore structures or pressure vessels, K-71TM ensures structural integrity with every weld.

Why Choose Flux Cored Welding Wire for High Tensile Steel?

This wire provides 65 J impact strength at –20°C without requiring PWHT, making it perfect for low-temperature environments. Its compatibility with both CO₂ and Ar+20% CO₂ shielding gases, along with DC(+) polarity, guarantees efficiency in demanding industrial settings.

Moreover, K-71TM supports all welding positions — flat, horizontal, overhead, vertical up/down — and maintains high mechanical properties with minimal spatter.
