Precious Metal 830 Silver-H01 vs 830 Silver-H08
Precious Metal · 830 Silver temper comparison
830 Silver-H01 and 830 Silver-H08 are two conditions of the same precious metal grade, 830 Silver: H01 (quarter hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. 830 Silver-H08 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 250 MPa (36.3 ksi) for 830 Silver-H01, about 92% more; tensile strength follows at 525 MPa (76.1 ksi) vs 355 MPa (51.5 ksi). In exchange, 830 Silver-H01 is the more ductile: elongation 20% versus 2% for 830 Silver-H08, and 830 Silver-H08 is harder (143 HB vs 86 HB). 830 Silver-H01 runs hotter in service (150°C vs 100°C continuous). On the shop floor, 830 Silver-H08 machines more easily (very good vs good) and 830 Silver-H01 welds better (68 vs 58 out of 100).
830 Silver-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
830 Silver-H08Choose it when strength drives the design, or when the part is machined in volume.
830 Silver-H01 vs 830 Silver-H08: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all precious metal grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

830 Silver-H01 vs 830 Silver-H08 — frequently asked
Is 830 Silver-H08 stronger than 830 Silver-H01?
Yes. 830 Silver-H08 has a typical yield strength of 480 MPa (69.6 ksi) against 250 MPa (36.3 ksi) for 830 Silver-H01 — about 92% more. Tensile strength is 525 MPa (76.1 ksi) vs 355 MPa (51.5 ksi).
Which condition does FabDigit quote by default, H01 or H08?
O is the default 830 Silver condition in the FabDigit quote flow (neither H01 nor H08). 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, 830 Silver-H01 or 830 Silver-H08?
830 Silver-H08. Its machinability rates very good (70/100) against good (60/100) for 830 Silver-H01; for welding the order is 830 Silver-H01 first (good, 68/100) then 830 Silver-H08 (good, 58/100).
