The Josef Gas A2 Tool Steel TIG Rod (SKU: ER937-116) is a high-performance filler metal designed specifically for the repair and fabrication of tools, dies, and industrial cutting surfaces. Manufactured to meet strict metallurgical standards, this 1/16-inch diameter rod is formulated from AISI A2 air-hardening tool steel. This alloy is renowned in the industrial sector for its exceptional dimensional stability during heat treatment and its balanced profile of wear resistance and toughness. Unlike oil-hardening or water-hardening steels, A2 minimizes distortion, making it the preferred choice for intricate die sections and precision tooling components.
Each 10 lb tube contains 36-inch cut lengths, cleaned and processed to ensure a contaminant-free surface. This attention to surface quality is critical in TIG (GTAW) welding, where even minor impurities can lead to porosity or inclusions in the weld deposit. The A2 composition typically includes Chromium (approx. 5%) and Molybdenum (approx. 1%), which contributes to its deep hardening characteristics and high compressive strength. When welded, the deposit exhibits air-hardening properties, meaning it achieves significant hardness simply by cooling in still air, although proper preheat and post-weld heat treatment (PWHT) are recommended to achieve optimal mechanical properties and prevent cracking in the Heat Affected Zone (HAZ).
Industrial MRO professionals rely on this filler metal for extending the service life of blanking dies, forming dies, shears, punches, and thread rolling dies. By rebuilding worn edges rather than replacing entire components, facilities can achieve substantial cost savings. The rod flows smoothly under 100% Argon shielding gas, providing a controllable puddle that allows for precise buildup on edges and corners. Whether used for correcting machining errors, modifying design features, or repairing service wear, the Josef A2 TIG rod delivers consistent, high-quality results compatible with base metals of similar composition.
