LNXS2610-35 - Lincoln Blue Max MIG 308LSi 0.035" Stainless Wire - 25lb Spool

Technical Overview: Lincoln Electric Blue Max® MIG 308LSi

The Lincoln Electric Blue Max® MIG 308LSi (SKU: LNXS2610-35) is a premium austenitic stainless steel solid wire designed for the Gas Metal Arc Welding (GMAW) process. This consumable is formulated with a nominal composition of 20% chromium and 10% nickel, adhering to AWS A5.9 and ASME SFA-5.9 standards with an ER308LSi classification. The 'Si' designation indicates a higher silicon content (0.65-1.00%), which is critical for improving the fluidity of the weld pool, thereby enhancing wetting action and bead appearance.

This 0.035-inch (0.9 mm) diameter wire is supplied on a 25 lb (11.3 kg) steel spool, suitable for industrial wire feeders. The chemical composition is tightly controlled to ensure consistent mechanical properties and corrosion resistance. Specifically, the carbon content is maintained below 0.03% to mitigate the risk of carbide precipitation and intergranular corrosion, making it ideal for welding 304 and 304L base metals. It is also compatible with Types 301, 302, and 321 stabilized stainless steels.

Blue Max® MIG 308LSi exhibits a ferrite number (FN) typically in the range of 8-12, providing excellent resistance to cracking. The wire is manufactured with Lincoln Electric's proprietary surface lubricants to ensure smooth feeding and stable arc transfer, reducing downtime associated with liner clogging or burn-backs. It is recommended for use with argon-based shielding gas blends, such as 98% Argon/2% Oxygen or 97% Argon/3% CO2, to optimize arc characteristics and penetration profiles.
