Abstract Scope |
H-13 tools steel’s relative hardness, resistance to thermal fatigue, and high tolerance of thermal shock, make it very desirable for use in forging, pressing, and extrusion processes. H-13 is however typically very expensive when compared to other steel compositions making it desirable to encase a lower cost alloy with H-13. This configuration allows for the benefits of H-13 tooling to be realized, at a considerably reduced cost. To demonstrate the viability of this concept, a pressing tool was fabricated using a Wire Arc Additive Manufacturing (WAAM) process.
Initial materials testing was conducted on a multi-material wall consisting of one section of H-13 tool steel, and one section of 410NiNo. This testing generated favorable results and subsequently a pressing tool was fabricated for evaluation. Utilization of a Multi-Material WAAM process to fabricate large tooling in this manner could yield significant improvements in material cost, manufacturing agility, and supply chain complexity. |
