Steel EN19 Annealed vs EN19-CR
Steel · EN19 temper comparison
EN19 Annealed and EN19-CR are two conditions of the same steel grade, EN19: Annealed versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. EN19-CR is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 417 MPa (60.5 ksi) for EN19 Annealed, about 39% more; tensile strength follows at 720 MPa (104 ksi) vs 655 MPa (95 ksi). In exchange, EN19 Annealed is the more ductile: elongation 25.7% versus 15% for EN19-CR, and EN19-CR is harder (217 HB vs 197 HB).
EN19 AnnealedChoose it when the part is bent, formed or impact-loaded.
EN19-CRChoose it when strength drives the design.
EN19 Annealed vs EN19-CR: 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.

EN19 Annealed vs EN19-CR — frequently asked
Is EN19-CR stronger than EN19 Annealed?
Yes. EN19-CR has a typical yield strength of 580 MPa (84.1 ksi) against 417 MPa (60.5 ksi) for EN19 Annealed — about 39% more. Tensile strength is 720 MPa (104 ksi) vs 655 MPa (95 ksi).
Which condition does FabDigit quote by default, Annealed or CR?
HR is the default EN19 condition in the FabDigit quote flow (neither Annealed nor CR). 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, EN19 Annealed or EN19-CR?
EN19 Annealed. Its weldability rates fair (45/100) against fair (40/100) for EN19-CR.
