Precious Metal PtRu10-H01 vs PtRu10-H04

Precious Metal · PtRu10 temper comparison

PtRu10-H01 and PtRu10-H04 are two conditions of the same precious metal grade, PtRu10: H01 (quarter hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. PtRu10-H04 is the stronger of the two: yield strength 820 MPa (119 ksi) against 450 MPa (65.3 ksi) for PtRu10-H01, about 82% more; tensile strength follows at 930 MPa (135 ksi) vs 650 MPa (94.3 ksi). In exchange, PtRu10-H01 is the more ductile: elongation 15% versus 3% for PtRu10-H04, and PtRu10-H04 is harder (245 HB vs 176 HB). PtRu10-H01 runs hotter in service (300°C vs 200°C continuous). On the shop floor, PtRu10-H01 welds better (65 vs 55 out of 100).

PtRu10-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

PtRu10-H04Choose it when strength drives the design.

PtRu10-H01 vs PtRu10-H04 — frequently asked

Is PtRu10-H04 stronger than PtRu10-H01?

Yes. PtRu10-H04 has a typical yield strength of 820 MPa (119 ksi) against 450 MPa (65.3 ksi) for PtRu10-H01 — about 82% more. Tensile strength is 930 MPa (135 ksi) vs 650 MPa (94.3 ksi).

Which condition does FabDigit quote by default, H01 or H04?

Annealed is the default PtRu10 condition in the FabDigit quote flow (neither H01 nor H04). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, PtRu10-H01 or PtRu10-H04?

PtRu10-H04. Its machinability rates fair (40/100) against poor (33/100) for PtRu10-H01; for welding the order is PtRu10-H01 first (good, 65/100) then PtRu10-H04 (good, 55/100).
