StarBlaze MIG 308L
AWS A5.9: ER 308L | EN ISO 14343-A: W 19 9 L
StarBlaze MIG 308L is an extra low carbon stainless steel MIG wire suitable for welding austenitic stainless steels such as AISI 301, 302, 304, 304L, 308, and 308L. With a balanced Cr/Ni composition (20Cr/9Ni) and controlled ferrite between 5–10%, it ensures excellent corrosion resistance and reliable mechanical performance. The wire is specially processed with anti-spatter silicone and ester coating for improved feedability and arc stability. Precision layer winding ensures smooth feeding, while its cast/helix control ensures ideal “pay-off” during use. Widely used in food processing, chemical industries, and boiler or piping fabrication.
