Nickel Alloy Inconel 600 1/4H vs Inconel 600-ANN
Nickel Alloy · Inconel 600 temper comparison
Inconel 600 1/4H and Inconel 600-ANN are two conditions of the same nickel alloy grade, Inconel 600: 1/4H (quarter hard) versus ANN (annealed). The chemistry is identical, so every difference below comes from the condition. Inconel 600 1/4H is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 255 MPa (37 ksi) for Inconel 600-ANN, about 104% more; tensile strength follows at 750 MPa (109 ksi) vs 620 MPa (89.9 ksi). In exchange, Inconel 600-ANN is the more ductile: elongation 42% versus 22% for Inconel 600 1/4H, and Inconel 600 1/4H is harder (210 HB vs 150 HB). Inconel 600-ANN runs hotter in service (1,100°C vs 550°C continuous). On the shop floor, Inconel 600-ANN welds better (80 vs 70 out of 100).

Inconel 600 1/4H vs Inconel 600-ANN: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy 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.

Inconel 600 1/4H vs Inconel 600-ANN — frequently asked
Is Inconel 600 1/4H stronger than Inconel 600-ANN?
Yes. Inconel 600 1/4H has a typical yield strength of 520 MPa (75.4 ksi) against 255 MPa (37 ksi) for Inconel 600-ANN — about 104% more. Tensile strength is 750 MPa (109 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, 1/4H or ANN?
ANN is the default Inconel 600 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, Inconel 600 1/4H or Inconel 600-ANN?
Inconel 600 1/4H, by a small margin. Both rate poor for machinability — 33/100 against 28/100 for Inconel 600-ANN; for welding the order is Inconel 600-ANN first (very good, 80/100) then Inconel 600 1/4H (very good, 70/100).
