Precious Metal Silver 925 1/2H vs Silver 925-PH

Precious Metal · Silver 925 temper comparison

Silver 925 1/2H and Silver 925-PH are two conditions of the same precious metal grade, Silver 925: 1/2H (half hard) versus PH (pre-hardened). The chemistry is identical, so every difference below comes from the condition. Silver 925-PH is the stronger of the two: yield strength 400 MPa (58 ksi) against 260 MPa (37.7 ksi) for Silver 925 1/2H, about 54% more; tensile strength follows at 470 MPa (68.2 ksi) vs 380 MPa (55.1 ksi). In exchange, Silver 925 1/2H is the more ductile: elongation 12% versus 6% for Silver 925-PH, and Silver 925-PH is harder (132 HB vs 95 HB). Silver 925-PH runs hotter in service (200°C vs 150°C continuous). On the shop floor, Silver 925 1/2H welds better (good vs fair).

Silver 925 1/2HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.

Silver 925-PHChoose it when strength drives the design, or when the part sees heat.

Silver 925 1/2H vs Silver 925-PH — frequently asked

Is Silver 925-PH stronger than Silver 925 1/2H?

Yes. Silver 925-PH has a typical yield strength of 400 MPa (58 ksi) against 260 MPa (37.7 ksi) for Silver 925 1/2H — about 54% more. Tensile strength is 470 MPa (68.2 ksi) vs 380 MPa (55.1 ksi).

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

O is the default Silver 925 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, Silver 925 1/2H or Silver 925-PH?

Silver 925-PH, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for Silver 925 1/2H; for welding the order is Silver 925 1/2H first (good, 55/100) then Silver 925-PH (fair, 45/100).
