Description
The ER630 MIG Wire 1.2mm 15kg spool is a high-performance welding wire specifically formulated for welding martensitic precipitation hardening stainless steels, such as 17-4PH (Type 630). It’s ideal for applications that require high strength, good toughness, and excellent corrosion resistance in both welded and heat-treated conditions.
This ER630 MIG Wire is perfect for use in aerospace, nuclear, marine, and petrochemical industries, where precision and durability are critical. The wire offers excellent weldability and produces strong, crack-resistant joints when used correctly.
With its 1.2mm diameter, this wire provides a stable arc, smooth feeding, and reduced spatter, making it suitable for semi-automated and robotic welding operations. When post-weld heat-treated, it achieves similar strength and hardness properties as the base 17-4PH stainless steel, allowing for consistent performance throughout the component.
Shielding gases like 100% Argon or Argon with CO₂ mixtures ensure clean, smooth welds. The 15kg spool is ideal for long production runs and heavy-duty applications where downtime is costly.
