Precious Metal 14K-ANN vs 14K-H02

Precious Metal · 14K temper comparison

14K-ANN and 14K-H02 are two conditions of the same precious metal grade, 14K: ANN (annealed) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. 14K-H02 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 220 MPa (31.9 ksi) for 14K-ANN, about 114% more; tensile strength follows at 600 MPa (87 ksi) vs 400 MPa (58 ksi). In exchange, 14K-ANN is the more ductile: elongation 35% versus 10% for 14K-H02, and 14K-H02 is harder (176 HB vs 133 HB). 14K-ANN runs hotter in service (250°C vs 180°C continuous). On the shop floor, 14K-H02 machines more easily (very good vs good).

14K-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

14K-H02Choose it when strength drives the design, or when the part is machined in volume.

14K-ANN vs 14K-H02 — frequently asked

Is 14K-H02 stronger than 14K-ANN?

Yes. 14K-H02 has a typical yield strength of 470 MPa (68.2 ksi) against 220 MPa (31.9 ksi) for 14K-ANN — about 114% more. Tensile strength is 600 MPa (87 ksi) vs 400 MPa (58 ksi).

Which condition does FabDigit quote by default, ANN or H02?

ANN is the default 14K condition in the FabDigit quote flow. 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, 14K-ANN or 14K-H02?

14K-H02. Its machinability rates very good (70/100) against good (55/100) for 14K-ANN; for welding the order is 14K-ANN first (very good, 80/100) then 14K-H02 (very good, 72/100).
