WM958T062T - D2 Tool Steel TIG Welding Rod - 1/16 Inch - 1lb Tube

Exocor D2 Tool Steel TIG Welding Rod - 1/16"

Restore your cutting edges and cold work tools with confidence using the Exocor D2 Tool Steel TIG Welding Rod. This 1/16" (1.6mm) filler metal is formulated to match AISI D2 tool steel, a legendary alloy in the machining and fabrication world known for its extreme abrasion resistance and deep hardening properties. Sold in a practical 1 lb tube, this product is perfect for tool and die shops, machine repair facilities, and specialty fabricators who need to perform critical repairs on hardened steel components.

D2 is characterized by its high carbon and high chromium content. This chemistry creates massive chromium carbides within the steel matrix, which act as a barrier against sliding wear and abrasion. This makes the Exocor D2 rod an excellent choice for building up surfaces on brick mold liners, forming dies, and punches that see repetitive friction. The 1/16" diameter offers excellent puddle control, allowing the welder to deposit material precisely on corners and edges where tool steel repairs are most frequently needed.

Welding Characteristics

Welding tool steel requires precision and the right filler metal. This rod is designed for the Gas Tungsten Arc Welding (GTAW/TIG) process using 100% Argon shielding gas. It flows smoothly and fuses well with D2 and similar high-carbon, high-chrome base metals. The resulting weld deposit is extremely hard and durable. While it offers incredible wear resistance, users should be aware that D2 is sensitive to thermal shock; therefore, preheating the workpiece (typically to 400°F - 600°F) is standard practice to prevent cracking during the welding process.

Key Applications

• Shear Blades: Rebuild chipped edges to extend blade life.
• Stamping Dies: Repair worn surfaces to maintain part tolerance.
• Punches: Restore the cutting face of high-impact punches.
• Plastic Injection Molds: Suitable for molds requiring high wear resistance.

Don't let worn tooling halt your production. Keep a tube of Exocor D2 TIG rod in your welding cabinet to ensure you can quickly address wear and tear on your most valuable cold work tools.
