Nickel Alloy Haynes 282-CW vs Haynes 282-HR
Nickel Alloy · Haynes 282 temper comparison
Haynes 282-CW and Haynes 282-HR are two conditions of the same nickel alloy grade, Haynes 282: CW (cold worked) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Haynes 282-CW is the stronger of the two: yield strength 900 MPa (131 ksi) against 640 MPa (92.8 ksi) for Haynes 282-HR, about 41% more; tensile strength follows at 1,150 MPa (167 ksi) vs 1,060 MPa (154 ksi). In exchange, Haynes 282-HR is the more ductile: elongation 40% versus 20% for Haynes 282-CW, and Haynes 282-CW is harder (285 HB vs 235 HB). Haynes 282-HR runs hotter in service (870°C vs 650°C continuous).
Haynes 282-CWChoose it when strength drives the design.
Haynes 282-HRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Haynes 282-CW vs Haynes 282-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.

Haynes 282-CW vs Haynes 282-HR — frequently asked
Is Haynes 282-CW stronger than Haynes 282-HR?
Yes. Haynes 282-CW has a typical yield strength of 900 MPa (131 ksi) against 640 MPa (92.8 ksi) for Haynes 282-HR — about 41% more. Tensile strength is 1,150 MPa (167 ksi) vs 1,060 MPa (154 ksi).
Which condition does FabDigit quote by default, CW or HR?
SA is the default Haynes 282 condition in the FabDigit quote flow (neither CW 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.
When should I choose Haynes 282-CW over Haynes 282-HR?
Pick Haynes 282-CW when strength drives the design. Pick Haynes 282-HR when the part is bent, formed or impact-loaded, or when the part sees heat.
