Description

ER318 MIG Wire 1.2mm – Stainless MIG Wire for Stabilized Austenitic Stainless Steels

The ER318 MIG Wire in 1.2mm diameter is a high-performance stainless steel welding wire designed specifically for welding stabilized stainless steels like 316Ti and 321. Supplied on a 15kg spool, this wire offers excellent corrosion resistance, smooth welding characteristics, and high mechanical integrity.

Designed for Welding Stabilized Stainless Grades

This ER318 MIG wire contains niobium (Nb) and/or titanium (Ti) stabilizers that prevent carbide precipitation during welding. As a result, it is ideal for 316Ti or 321 stainless steel, which require matching stabilized filler materials to maintain their corrosion-resistant properties in high-temperature or aggressive environments.

Thanks to its special formulation, the wire prevents intergranular corrosion and ensures long-term durability in welded structures.

Smooth Arc and Clean Weld Finish

With its excellent arc stability and low spatter characteristics, ER318 MIG wire ensures consistent, high-quality welds. It works well in spray and short-circuit transfer modes, which helps welders achieve clean beads with minimal post-weld cleanup. This efficiency translates to faster job completion and lower production costs.

Ideal for Food Processing, Marine, and Chemical Environments

ER318 is a popular choice in industries that require hygienic or corrosion-resistant stainless steel fabrications, such as:

  • Food and beverage production

  • Chemical and petrochemical plants

  • Marine and offshore structures

  • Pharmaceutical and dairy equipment

  • Heat exchangers and pressure vessels

Its corrosion resistance against acids and chlorides makes it ideal for demanding, high-moisture, or acidic conditions.
