ER880-116X36 - 880 Universal Maintenance TIG Rod - 1/16 in - 10lb Tube

High-Performance Metallurgy for Critical Repairs

The 880 Specialty TIG Welding Rod is a high-alloy filler metal designed for the most demanding maintenance and repair applications. Metallurgically, this alloy is a modified austenitic-ferritic stainless steel (often compared to a "Super 312" chemistry) that offers a unique combination of high tensile strength and excellent elongation. With a tensile strength approaching 120,000 PSI, it far outperforms standard ER70S-6 or 308L rods, making it indispensable for structural repairs where failure is not an option.

The secret to the 880's performance lies in its two-phase microstructure. The ferrite pool in the weld matrix acts as a trap for impurities and allows for the dissipation of shrinkage stresses during cooling. This mechanism renders the weld deposit virtually immune to hot cracking, even when welding on dirty, oily, or high-carbon base metals that would typically cause underbead cracking. For professional welders, this means you can confidently weld spring steels, manganese steels, and unknown alloys without the extensive pre-heat and post-heat procedures often required by other filler metals.

Technical Specifications & Usage

This 10lb package of 1/16" (1.6mm) rods is ideal for TIG (GTAW) welding using DCEN (Direct Current Electrode Negative). The alloy exhibits excellent corrosion resistance, comparable to 300-series stainless steels, and maintains its mechanical properties at elevated temperatures. It is also heat treatable and work-hardens in service, making it suitable for buildup applications on parts subject to heavy impact or metal-to-metal wear.

Why Choose 880?

• Extreme Crack Resistance: The high ferrite content prevents cracking in rigid restraints.
• High Yield Strength: Resists deformation under heavy loads.
• Versatility: One rod covers 90% of maintenance welding needs, reducing inventory.
• Machinability: Can be machined with standard carbide tools, despite its high strength.

Equip your shop with the 880 TIG rod and ensure you are prepared for any repair challenge that comes through the door.
