EX4130000000620T00 - Exocor ER4130 0.035" Chrome-Moly TIG Rod - 10lb Tube

Premium Exocor 4130 TIG Welding Rod for High-Strength Alloys

The Exocor 4130 0.035" TIG Rod is a high-quality low-alloy steel filler metal designed specifically for the Gas Tungsten Arc Welding (GTAW) of 4130 and 4140 base materials. Often referred to as "Chrome-Moly," these steels are renowned for their high strength-to-weight ratio and hardenability, making them a standard in the aerospace, motorsports, and oil and gas industries. This rod is formulated to deposit weld metal that matches the chemical and mechanical properties of the base plate, ensuring structural integrity under extreme stress.

One of the primary advantages of using Exocor 4130 filler metal is its response to heat treatment. When welding heat-treatable steels, it is crucial that the weld bead can be hardened and tempered to the same degree as the surrounding material to avoid weak points. This rod produces deposits that are fully heat-treatable, maintaining uniform hardness across the weldment. It is typically used with 100% Argon shielding gas and requires proper pre-heat and interpass temperature controls to prevent cracking, a common challenge with high-carbon low-alloy steels.

Packaged in a durable 10 lb tube, these 36-inch cut lengths are cleaned and processed to ensure a contaminant-free surface. This attention to surface quality reduces the risk of porosity and inclusions, providing the welder with a smooth, stable arc and excellent puddle control. Whether you are fabricating aircraft components, racing chassis, or high-pressure piping, Exocor 4130 delivers the reliability and performance required for critical applications.
