Precious Metal 830 Silver-H02 vs 830 Silver-H08
Precious Metal · 830 Silver temper comparison
830 Silver-H02 and 830 Silver-H08 are two conditions of the same precious metal grade, 830 Silver: H02 (half 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 330 MPa (47.9 ksi) for 830 Silver-H02, about 45% more; tensile strength follows at 525 MPa (76.1 ksi) vs 405 MPa (58.7 ksi). In exchange, 830 Silver-H02 is the more ductile: elongation 10% versus 2% for 830 Silver-H08, and 830 Silver-H08 is harder (143 HB vs 107 HB). 830 Silver-H02 runs hotter in service (150°C vs 100°C continuous).
830 Silver-H02Choose 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.
830 Silver-H02 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-H02 vs 830 Silver-H08 — frequently asked
Is 830 Silver-H08 stronger than 830 Silver-H02?
Yes. 830 Silver-H08 has a typical yield strength of 480 MPa (69.6 ksi) against 330 MPa (47.9 ksi) for 830 Silver-H02 — about 45% more. Tensile strength is 525 MPa (76.1 ksi) vs 405 MPa (58.7 ksi).
Which condition does FabDigit quote by default, H02 or H08?
O is the default 830 Silver condition in the FabDigit quote flow (neither H02 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-H02 or 830 Silver-H08?
830 Silver-H08. Its machinability rates very good (70/100) against good (65/100) for 830 Silver-H02; for welding the order is 830 Silver-H02 first (good, 65/100) then 830 Silver-H08 (good, 58/100).
