ER938-116 - D2 Tool Steel TIG Welding Rod 1/16" - 10lb Tube

High-Performance D2 Tool Steel TIG Rods

The ER938-116 D2 Tool Steel TIG Rod is a premium welding consumable designed specifically for the repair and fabrication of tools and dies made from AISI D2 steel. This 1/16-inch (1.6mm) diameter rod is supplied in a 10lb protective tube, ensuring the material remains clean and free from contaminants until use. D2 is a high-carbon, high-chromium, air-hardening tool steel known for its exceptional wear resistance and high compressive strength. It is widely used in the industry for cold work applications where resistance to abrasion is critical.

When welding with this alloy, the deposit exhibits properties very similar to the base metal, allowing for seamless repairs on expensive tooling components. The high chromium content (approximately 12%) provides mild corrosion resistance in the hardened condition, while the high carbon content ensures the material can achieve significant hardness (typically 55-60 HRC) after proper heat treatment. This rod is engineered to provide a stable arc and smooth flow, essential for the precise buildup work often required on intricate die edges and punch faces.

Technical Specifications & Metallurgy

The metallurgy of this D2 rod is balanced to minimize the risk of cracking, although proper preheat and post-weld heat treatment (PWHT) procedures are strongly recommended due to the air-hardening nature of the base material. The rod is manufactured to strict tolerances regarding diameter and chemical composition, ensuring consistent performance from batch to batch. It is suitable for use with 100% Argon shielding gas on DCEN polarity.
