Nickel Alloy Inconel 600 1/2H vs Inconel 600 1/4H
Nickel Alloy · Inconel 600 temper comparison
Inconel 600 1/2H and Inconel 600 1/4H are two conditions of the same nickel alloy grade, Inconel 600: 1/2H (half hard) versus 1/4H (quarter hard). The chemistry is identical, so every difference below comes from the condition. Inconel 600 1/2H is the stronger of the two: yield strength 700 MPa (102 ksi) against 520 MPa (75.4 ksi) for Inconel 600 1/4H, about 35% more; tensile strength follows at 880 MPa (128 ksi) vs 750 MPa (109 ksi). In exchange, Inconel 600 1/4H is the more ductile: elongation 22% versus 12% for Inconel 600 1/2H, and Inconel 600 1/2H is harder (250 HB vs 210 HB). Inconel 600 1/4H runs hotter in service (550°C vs 480°C continuous).
Inconel 600 1/2HChoose it when strength drives the design.
Inconel 600 1/4HChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Inconel 600 1/2H vs Inconel 600 1/4H: 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 1/2H vs Inconel 600 1/4H — frequently asked
Is Inconel 600 1/2H stronger than Inconel 600 1/4H?
Yes. Inconel 600 1/2H has a typical yield strength of 700 MPa (102 ksi) against 520 MPa (75.4 ksi) for Inconel 600 1/4H — about 35% more. Tensile strength is 880 MPa (128 ksi) vs 750 MPa (109 ksi).
Which condition does FabDigit quote by default, 1/2H or 1/4H?
ANN is the default Inconel 600 condition in the FabDigit quote flow (neither 1/2H nor 1/4H). 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 welds better, Inconel 600 1/2H or Inconel 600 1/4H?
Inconel 600 1/4H. Its weldability rates very good (70/100) against good (65/100) for Inconel 600 1/2H.
