Precious Metal 830 Silver-F vs 830 Silver-H04
Precious Metal · 830 Silver temper comparison
830 Silver-F and 830 Silver-H04 are two conditions of the same precious metal grade, 830 Silver: F (as fabricated) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. 830 Silver-H04 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 115 MPa (16.7 ksi) for 830 Silver-F, about 3.7 times as much; tensile strength follows at 470 MPa (68.2 ksi) vs 260 MPa (37.7 ksi). In exchange, 830 Silver-F is the more ductile: elongation 18% versus 4% for 830 Silver-H04, and 830 Silver-H04 is harder (128 HB vs 65 HB). 830 Silver-F runs hotter in service (300°C vs 120°C continuous). On the shop floor, 830 Silver-H04 machines more easily (68 vs 58 out of 100).
830 Silver-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
830 Silver-H04Choose it when strength drives the design, or when the part is machined in volume.
830 Silver-F vs 830 Silver-H04: 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-F vs 830 Silver-H04 — frequently asked
Is 830 Silver-H04 stronger than 830 Silver-F?
Yes. 830 Silver-H04 has a typical yield strength of 420 MPa (60.9 ksi) against 115 MPa (16.7 ksi) for 830 Silver-F — about 3.7 times as much. Tensile strength is 470 MPa (68.2 ksi) vs 260 MPa (37.7 ksi).
Which condition does FabDigit quote by default, F or H04?
O is the default 830 Silver condition in the FabDigit quote flow (neither F 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, 830 Silver-F or 830 Silver-H04?
830 Silver-H04, by a small margin. Both rate good for machinability — 68/100 against 58/100 for 830 Silver-F.
