Description

SUPERMIG 308LSi is an extra low carbon 20 Cr/ 9 Ni stainless steel filler wire suitable for MIG welding of austenitic stainless steels such as 18 Cr /8 Ni type, AISI 301, 302, 304, 304L, 308 and 308L type of steels. Excellent corrosion resistance and good mechanical properties. Ferrite is controlled between 5-10%.Si~0.80 content improves weldability and bead appearance.
This all – position, quality MIG wire is ideally suited for joining common austenitic stainless steel grades referred to as “18-8” steels. It is specially processed to provide superior feeding and arc stability. Precision layer winding technologies ensure smooth, virtually trouble-free feeding. Typical applications includes welding of austenitic stainless steels like AISI 301, 302, 304, 304L, 308 and 308L type generally used in food processing and chemical industries, as well as for pipes, tubes, boilers.

Welding Directions

MIG welding can be performed as short, spray or pulsed arc. Short arc is preferably used for thin gauges, both for horizontal and positional welding. Spray arc increases the deposition rate. Welding with pulsed arc gives excellent possibilities for a good result in varying plate thicknesses in all positions. The highest flexibility using pulsed arc is achieved with 1.20 mm wire.

Corrosion Resistance

Corresponding to ER308LSi, i.e. fairly good under severe conditions such as oxidising and cold dilute reducing acids.

Storage

Keep dry and avoid condensation.
