StarBlaze MIG 304L
AWS A5.9: ER 304L | EN ISO 14343-A: W 19 9 L
StarBlaze MIG 304L is a low-carbon stainless steel MIG wire designed for welding austenitic stainless steels like AISI 301, 302, 304, and 304L. It offers excellent corrosion resistance, good mechanical strength, and high resistance to intergranular corrosion due to its extra-low carbon content. Controlled ferrite content (3–8%) provides balanced toughness and crack resistance. Precision layer-wound for smooth, consistent feedability, this wire is ideal for applications in the food processing, chemical, and boiler industries.
- Diameters: 0.8 mm, 1.0 mm, 1.2 mm
- Pack size: 12.50 kg
