EX33000000000350M0 - Exocor ER330 Stainless Steel MIG Wire .035 33lb Spool

Industrial Grade ER330 Stainless Steel MIG Wire

The Exocor ER330 MIG Welding Wire is a premium consumable designed for the fabrication and repair of cast and wrought alloys of similar chemical composition. Engineered with a nominal composition of 35% Nickel and 15% Chromium, this wire is classified under AWS A5.9 specifications. It is specifically formulated to withstand extreme thermal environments where resistance to oxidation and carburization is paramount. The high nickel content not only enhances the alloy's resistance to stress corrosion cracking but also ensures stability and strength at temperatures reaching up to 1800°F (980°C).

This fully austenitic alloy is widely utilized in the petrochemical and thermal processing industries. Common applications include the welding of furnace components, heat treatment baskets, heat exchangers, and high-temperature fans. Because the weld metal remains fully austenitic, it does not contain ferrite, which typically aids in preventing hot cracking in other stainless steels. Consequently, this wire requires precise manufacturing controls to ensure purity and consistency, which Exocor delivers in this 33lb spool format. The wire is precision layer wound to prevent tangling and ensure smooth feeding through standard MIG gun liners, reducing downtime in automated or high-volume manual welding operations.

Industrial procurement specialists should note that while ER330 is excellent for heat resistance, the lack of ferrite makes the weld pool sensitive to heat input. It is recommended for use in environments where the base material is subject to thermal shock and cyclic heating. The 0.035-inch diameter offers versatility for welding various material thicknesses, providing a balance between deposition rate and puddle control. This product is an essential inventory item for facilities maintaining heat-treating equipment or fabricating high-temperature alloy structures.
