GB/T 10045 T494T1-1C1A AWS A5.20 E71T-1C-J ISO 17632-B-T494T1-1C1A JIS Z3313 T494T1-1CA

Application: Applicable to the welding of 490MPa high-strength steel structure, mostly the welding of steel structure for ships, mechanical manufacturing, containers, petrochemical engineering, bridges etc.

Characteristics: Titanium oxide-based gas-shielded flux-cored welding wire features excellent welding process performance, with a soft and stable arc, low spatter, easy slag removal, attractive weld formation and high welding efficiency. The deposited metal delivers outstanding low-temperature toughness at -40℃ and excellent crack resistance.

Power Polarity: DC Reverse Polarity (DC+)

Shielding Gas: 100% CO₂
