Steel S235JR-CD vs S235JR-CR
Steel · S235JR temper comparison
S235JR-CD and S235JR-CR are two conditions of the same steel grade, S235JR: CD (cold drawn) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. S235JR-CD is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 290 MPa (42.1 ksi) for S235JR-CR, about 17% more; tensile strength follows at 450 MPa (65.3 ksi) vs 400 MPa (58 ksi). In exchange, S235JR-CR is the more ductile: elongation 22% versus 14% for S235JR-CD, and S235JR-CD is harder (150 HB vs 130 HB).
S235JR-CDChoose it when strength drives the design.
S235JR-CRChoose it when the part is bent, formed or impact-loaded.
S235JR-CD vs S235JR-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.

S235JR-CD vs S235JR-CR — frequently asked
Is S235JR-CD stronger than S235JR-CR?
Yes. S235JR-CD has a typical yield strength of 340 MPa (49.3 ksi) against 290 MPa (42.1 ksi) for S235JR-CR — about 17% more. Tensile strength is 450 MPa (65.3 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, CD or CR?
HR is the default S235JR condition in the FabDigit quote flow (neither CD 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, S235JR-CD or S235JR-CR?
S235JR-CR. Its weldability rates excellent (95/100) against excellent (90/100) for S235JR-CD.
