15kg – 0.9mm ER80S-D2 Chrome Moly MIG Welding Wire Spool: High-Strength Solution for Critical Welding Projects

Product Description

Engineered for precision and durability, the COBRA ER80S-D2 Chrome Moly MIG Welding Wire is a premium solid wire designed for gas-shielded (GMAW) welding of high-strength steels. With a 15kg spool and 0.9mm diameter, it delivers consistent arc performance and superior mechanical properties, making it ideal for demanding industrial applications.

Core Selling Points

• AWS ER80S-D2 classification for reliable high-strength welds
• Mn-Mo alloy composition ensures 550MPa minimum yield strength
• Compatible with CO2 or Argon/CO2 mixed gas (ER90S-D2 performance with mixed gas)
• Optimized for AISI 4130/4140, Q&T plates, and line boring applications
• Enhanced toughness for stress-relieved joints and heavy-duty use

Key Specifications

Applications

Perfect for welding stressed-relieved AISI 4130/4140 components, quenched and tempered (Q&T) plate joints, and line boring operations. Ideal for automotive, aerospace, and heavy machinery manufacturing where structural integrity and toughness are critical.

Core Performance

Delivers stable arc ignition, minimal spatter, and excellent bead appearance. The Mn-Mo alloy system ensures high tensile strength and impact resistance, even in low-temperature environments. Compatible with both CO2 (ER80S-D2) and Argon/CO2 mix (ER90S-D2 equivalent strength), offering flexibility for diverse welding conditions.

Quality Assurance

Manufactured under strict ISO 9001 quality control standards. Each spool undergoes rigorous testing for chemical composition, mechanical properties, and surface quality to ensure consistent performance and reliability.

Differentiation

Unlike standard MIG wires, our ER80S-D2 offers dual-classification capability (ER80/ER90) via gas selection, reducing inventory costs. The optimized wire chemistry provides superior toughness compared to generic Mn-Si wires, making it the preferred choice for critical structural welds.

FAQ

Q: What gas should I use with this wire?
A: Use 100% CO2 for ER80S-D2 classification or Argon/CO2 mix for ER90S-D2 strength levels.

Q: Is this wire suitable for AISI 4140 steel?
A: Yes, it is specifically formulated for welding AISI 4130/4140 and similar high-strength alloys.

Q: What is the recommended amperage range?
A: 140-220A (varies by gas type and joint design; consult welding procedure specifications).
