Precious Metal Pd99.9 Annealed vs Pd99.9-H04

Precious Metal · Pd99.9 temper comparison

Pd99.9 Annealed and Pd99.9-H04 are two conditions of the same precious metal grade, Pd99.9: Annealed versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. Pd99.9-H04 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 55 MPa (7.98 ksi) for Pd99.9 Annealed, about 5.2 times as much; tensile strength follows at 330 MPa (47.9 ksi) vs 180 MPa (26.1 ksi). In exchange, Pd99.9 Annealed is the more ductile: elongation 35% versus 3% for Pd99.9-H04, and Pd99.9-H04 is harder (100 HB vs 40 HB). Pd99.9 Annealed runs hotter in service (500°C vs 250°C continuous). On the shop floor, Pd99.9-H04 machines more easily (fair vs poor).

Pd99.9 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Pd99.9-H04Choose it when strength drives the design, or when the part is machined in volume.
