Steel 5130 Annealed vs 5130-CD
Steel · 5130 temper comparison
5130 Annealed and 5130-CD are two conditions of the same steel grade, 5130: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 5130-CD is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 380 MPa (55.1 ksi) for 5130 Annealed, about 53% more; tensile strength follows at 680 MPa (98.6 ksi) vs 590 MPa (85.6 ksi). In exchange, 5130 Annealed is the more ductile: elongation 26% versus 12% for 5130-CD, and 5130-CD is harder (200 HB vs 170 HB). On the shop floor, 5130 Annealed welds better (50 vs 40 out of 100).

5130-CDChoose it when strength drives the design.
5130 Annealed vs 5130-CD: 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.

5130 Annealed vs 5130-CD — frequently asked
Is 5130-CD stronger than 5130 Annealed?
Yes. 5130-CD has a typical yield strength of 580 MPa (84.1 ksi) against 380 MPa (55.1 ksi) for 5130 Annealed — about 53% more. Tensile strength is 680 MPa (98.6 ksi) vs 590 MPa (85.6 ksi).
Which condition does FabDigit quote by default, Annealed or CD?
HR is the default 5130 condition in the FabDigit quote flow (neither Annealed nor CD). 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, 5130 Annealed or 5130-CD?
5130 Annealed. Its weldability rates fair (50/100) against fair (40/100) for 5130-CD.
