Nickel 205-H vs Nickel 205-HR
Nickel Alloy · Nickel 205 temper comparison
Nickel 205-H and Nickel 205-HR are two conditions of the same nickel alloy grade, Nickel 205: H (hardened) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Nickel 205-H is the stronger of the two: yield strength 690 MPa (100 ksi) against 200 MPa (29 ksi) for Nickel 205-HR, about 3.5 times as much; tensile strength follows at 760 MPa (110 ksi) vs 500 MPa (72.5 ksi). In exchange, Nickel 205-HR is the more ductile: elongation 40% versus 5% for Nickel 205-H, and Nickel 205-H is harder (215 HB vs 110 HB). Nickel 205-HR runs hotter in service (315°C vs 260°C continuous). On the shop floor, Nickel 205-H machines more easily (fair vs poor) and Nickel 205-HR welds better (80 vs 70 out of 100).
Nickel 205-HChoose it when strength drives the design, or when the part is machined in volume.
Nickel 205-HRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Nickel 205-H vs Nickel 205-HR: 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.

Nickel 205-H vs Nickel 205-HR — frequently asked
Is Nickel 205-H stronger than Nickel 205-HR?
Yes. Nickel 205-H has a typical yield strength of 690 MPa (100 ksi) against 200 MPa (29 ksi) for Nickel 205-HR — about 3.5 times as much. Tensile strength is 760 MPa (110 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, H or HR?
ANN is the default Nickel 205 condition in the FabDigit quote flow (neither H nor HR). 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, Nickel 205-H or Nickel 205-HR?
Nickel 205-H. Its machinability rates fair (42/100) against poor (32/100) for Nickel 205-HR; for welding the order is Nickel 205-HR first (very good, 80/100) then Nickel 205-H (very good, 70/100).
