Steel DC53 Annealed vs DC53 HT 58-60 HRC
Steel · DC53 temper comparison
DC53 Annealed and DC53 HT 58-60 HRC are two conditions of the same steel grade, DC53: Annealed versus HT 58-60 HRC (hardened & tempered to 58-60 HRC). The chemistry is identical, so every difference below comes from the condition. DC53 HT 58-60 HRC is the stronger of the two: yield strength 1,650 MPa (239 ksi) against 550 MPa (79.8 ksi) for DC53 Annealed, about 3.0 times as much; tensile strength follows at 1,950 MPa (283 ksi) vs 850 MPa (123 ksi). In exchange, DC53 Annealed is the more ductile: elongation 12% versus 1.5% for DC53 HT 58-60 HRC, and DC53 HT 58-60 HRC is harder (630 HB vs 230 HB). DC53 Annealed runs hotter in service (500°C vs 400°C continuous) and DC53 Annealed conducts heat better (23 W/m·K vs 20.5 W/m·K). On the shop floor, DC53 Annealed machines more easily (fair vs not recommended) and DC53 Annealed welds better (poor vs not recommended).

DC53 Annealed vs DC53 HT 58-60 HRC: 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.

DC53 Annealed vs DC53 HT 58-60 HRC — frequently asked
Is DC53 HT 58-60 HRC stronger than DC53 Annealed?
Yes. DC53 HT 58-60 HRC has a typical yield strength of 1,650 MPa (239 ksi) against 550 MPa (79.8 ksi) for DC53 Annealed — about 3.0 times as much. Tensile strength is 1,950 MPa (283 ksi) vs 850 MPa (123 ksi).
Which condition does FabDigit quote by default, Annealed or HT 58-60 HRC?
Annealed is the default DC53 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.
Which is easier to machine, DC53 Annealed or DC53 HT 58-60 HRC?
DC53 Annealed. Its machinability rates fair (40/100) against not recommended (10/100) for DC53 HT 58-60 HRC; for welding the order is DC53 Annealed first (poor, 20/100) then DC53 HT 58-60 HRC (not recommended, 8/100).
