312 Stainless Steel MIG Wire 5kg

312 Stainless Steel MIG Wire suitable for joining difficult to weld steels such as tool and spring steel. Also for dissimilar materials and has a high resistance to weld metal cracking.
5kg spool.

Where you would use 312 dissimilar MIG wire:

Joining Dissimilar Steels

• Welding mild steel to stainless steel

• Welding carbon steels to alloy steels

• Welding manganese steels to stainless steels

Difficult-to-Weld Steels

• Ideal for high-carbon steels, hardened steels, spring steels, and tool steels.

• The high alloy content prevents cracking even in hard-to-weld base metals.

Repair & Maintenance Welding

• Widely used for repairing dies, tools, shafts, gears, and cast steels.

• Great for welding steels of unknown composition where youre unsure of the exact grade.

Buffer Layers

• Often used as a buffer or build-up layer before applying a harder or more wear-resistant overlay.

• Helps prevent dilution and cracking in hardfacing applications.

Corrosion & Heat Resistance

• Suitable in applications where joints need both strength and resistance to heat/corrosion, such as furnace parts or heavy equipment.
