Steel 1084-CR vs 1084 Normalized
Steel · 1084 temper comparison
1084-CR and 1084 Normalized are two conditions of the same steel grade, 1084: CR (cold rolled) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1084-CR is the stronger of the two: yield strength 700 MPa (102 ksi) against 525 MPa (76.1 ksi) for 1084 Normalized, about 33% more. In exchange, 1084 Normalized is the more ductile: elongation 11% versus 8% for 1084-CR, and 1084 Normalized is harder (293 HB vs 240 HB). 1084 Normalized runs hotter in service (400°C vs 250°C continuous).
1084-CRChoose it when strength drives the design.
1084 NormalizedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1084-CR vs 1084 Normalized: 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.

1084-CR vs 1084 Normalized — frequently asked
Is 1084-CR stronger than 1084 Normalized?
Yes. 1084-CR has a typical yield strength of 700 MPa (102 ksi) against 525 MPa (76.1 ksi) for 1084 Normalized — about 33% more. Tensile strength is 830 MPa (120 ksi) vs 1,010 MPa (146 ksi).
Which condition does FabDigit quote by default, CR or Normalized?
HR is the default 1084 condition in the FabDigit quote flow (neither CR nor Normalized). 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, 1084-CR or 1084 Normalized?
1084-CR. Its machinability rates fair (38/100) against poor (32/100) for 1084 Normalized.
