Description
ER347 MIG Wire 1.2mm – High-Performance Stainless Wire for Heat‑Resistant and Stabilized Steels
The ER347 MIG Wire in 1.2mm diameter is a stainless steel welding wire formulated for joining stabilized austenitic stainless steels like 321 and 347. Supplied in a 15kg spool, this wire offers strong mechanical properties, superior corrosion resistance, and excellent high-temperature strength, making it suitable for critical industrial applications.
Built for Stabilized Stainless Steels
This ER347 MIG wire contains columbium (niobium), which stabilizes the weld zone and prevents intergranular corrosion during high-temperature service. It is recommended for use with stainless steels that are stabilized with niobium or titanium, such as 321 and 347. By matching the filler metal to the base metal, you ensure strength and durability under extreme conditions.
In contrast to ER308L or ER316L, ER347 provides enhanced performance in environments with prolonged exposure to elevated heat.
Excellent Arc Control and Weld Appearance
Thanks to its stable arc characteristics and low spatter levels, ER347 MIG wire enables smooth, clean welds with minimal effort. It performs well in spray arc and short-circuit transfer modes, making it versatile across various welding setups. Additionally, it helps reduce time spent on grinding or polishing after welding.
Common Applications Across Multiple Industries
Because of its high-temperature tolerance and corrosion resistance, this wire is often used in:
-
Aerospace engine components
-
High-pressure steam piping
-
Marine heat exchangers and fittings
-
Chemical processing systems
-
Exhaust manifolds and stainless structures exposed to thermal cycling
Whether you’re welding for strength, appearance, or corrosion resistance, ER347 delivers reliable results.
