H13 High Tensile welding wire
H13 welding wire is a high-performance filler metal specifically designed for welding H13 tool steel, which is a hot work tool steel known for its excellent toughness, thermal fatigue resistance, and high-temperature strength. This welding wire is widely used in applications requiring resistance to heat, wear, and thermal cycling, such as die casting, forging, extrusion dies, and other hot work tooling.
- Repair and maintenance of H13 tool steel components, such as die casting molds, forging dies, and extrusion tools.
- Fabrication of new tools and dies requiring high thermal and mechanical performance.Welding of hot work tooling subjected to extreme temperatures and wear.

Preheat and post-weld heat treatment are often recommended to reduce the risk of cracking and to achieve optimal mechanical properties.
Proper shielding gas (e.g., argon for TIG welding) should be used to protect the weld pool from contamination.
