Steel A992-CR vs A992-HR
Steel · A992 temper comparison
A992-CR and A992-HR are two conditions of the same steel grade, A992: CR (cold rolled) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. A992-CR is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 380 MPa (55.1 ksi) for A992-HR, about 21% more; tensile strength follows at 560 MPa (81.2 ksi) vs 500 MPa (72.5 ksi). In exchange, A992-HR is the more ductile: elongation 25% versus 16% for A992-CR, and A992-CR is harder (170 HB vs 150 HB).
A992-CRChoose it when strength drives the design.
A992-HRChoose it when the part is bent, formed or impact-loaded.
A992-CR vs A992-HR: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel 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.

A992-CR vs A992-HR — frequently asked
Is A992-CR stronger than A992-HR?
Yes. A992-CR has a typical yield strength of 460 MPa (66.7 ksi) against 380 MPa (55.1 ksi) for A992-HR — about 21% more. Tensile strength is 560 MPa (81.2 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, CR or HR?
HR is the default A992 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.
When should I choose A992-CR over A992-HR?
Pick A992-CR when strength drives the design. Pick A992-HR when the part is bent, formed or impact-loaded.
