Description

Cigweld Supre-Cor 5 MIG Wire 15kg

The Cigweld Supre-Cor 5 MIG Wire 15kg is a second-generation E71T-5 fully basic flux cored wire engineered for critical structural welding applications requiring exceptional low-temperature toughness and ultra-low hydrogen performance. Designed for use with CO₂, Argon + CO₂ or equivalent shielding gases, Supre-Cor 5 delivers premium weld metal properties for demanding industrial environments.

Classified to:

• AWS/ASME-SFA A5.20: E71T-5 H4 / E71T-5MJ H4
• ISO AS/NZS 17632: B T 49 5 T5 1 M A U H5

Supre-Cor 5 offers “very low” hydrogen levels of <2.5 ml per 100g of deposited weld metal,making it suitable for high-integrity and crack-sensitive applications.

Outstanding Low-Temperature Impact Toughness

Supre-Cor 5 is designed to provide improved low-temperature impact toughness down to -50°C

Typical mechanical properties using Argon + 18–25% CO₂ shielding gas include:

• Yield Strength: 490 MPa
• Tensile Strength: 550 MPa
• Elongation: 28%
• CVN Impact: 90 J avg @ -51°C

These properties make Supre-Cor 5 ideal for structures exposed to cold service conditions or requiring high impact resistance.

Fully Basic Flux Core – Premium Weld Integrity

As a fully basic flux cored wire, Supre-Cor 5 provides:

• Improved resistance to hydrogen-induced cracking
• Superior weld metal cleanliness
• Excellent weld deposit properties in both “as welded” and stress-relieved conditions

Electrode negative (DCEN) polarity is preferred for optimal performance.

Designed for Critical Applications

Supre-Cor 5 is recommended for:

• Pressure vessels
• Offshore oil and gas platform structures
• Heavy earthmoving equipment
• Structural steel fabrication
• Multi-positional fillet and butt welding

Its improved positional capabilities in both 1.2mm and 1.6mm sizes enhance versatility across workshop and on-site fabrication.

Available Sizes – 15kg Spools

• 1.2mm – Part No. 720982
• 1.6mm – Part No. 720983

For fabricators requiring a fully basic, low hydrogen E71T-5 flux cored wire with outstanding impact performance and structural reliability, the Cigweld Supre-Cor 5 15kg spool delivers premium results.
