Precious Metal 800 Silver 1/2H vs 800 Silver-PH

Precious Metal · 800 Silver temper comparison

800 Silver 1/2H and 800 Silver-PH are two conditions of the same precious metal grade, 800 Silver: 1/2H (half hard) versus PH (pre-hardened). The chemistry is identical, so every difference below comes from the condition. 800 Silver-PH is the stronger of the two: yield strength 510 MPa (74 ksi) against 330 MPa (47.9 ksi) for 800 Silver 1/2H, about 55% more; tensile strength follows at 580 MPa (84.1 ksi) vs 400 MPa (58 ksi). In exchange, 800 Silver 1/2H is the more ductile: elongation 12% versus 4% for 800 Silver-PH, and 800 Silver-PH is harder (175 HB vs 118 HB). 800 Silver-PH runs hotter in service (250°C vs 180°C continuous) and 800 Silver-PH conducts heat better (345 W/m·K vs 310 W/m·K). On the shop floor, 800 Silver 1/2H welds better (good vs fair).

800 Silver 1/2HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.

800 Silver-PHChoose it when strength drives the design, or when the part sees heat.

800 Silver 1/2H vs 800 Silver-PH — frequently asked

Is 800 Silver-PH stronger than 800 Silver 1/2H?

Yes. 800 Silver-PH has a typical yield strength of 510 MPa (74 ksi) against 330 MPa (47.9 ksi) for 800 Silver 1/2H — about 55% more. Tensile strength is 580 MPa (84.1 ksi) vs 400 MPa (58 ksi).

Which condition does FabDigit quote by default, 1/2H or PH?

Annealed is the default 800 Silver condition in the FabDigit quote flow (neither 1/2H nor PH). 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, 800 Silver 1/2H or 800 Silver-PH?

800 Silver-PH, by a small margin. Both rate good for machinability — 65/100 against 58/100 for 800 Silver 1/2H; for welding the order is 800 Silver 1/2H first (good, 60/100) then 800 Silver-PH (fair, 45/100).
