Steel 1016 CARB-Q vs 1016-CD
Steel · 1016 temper comparison
1016 CARB-Q and 1016-CD are two conditions of the same steel grade, 1016: CARB-Q (carburized, quenched and low-temperature tempered) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1016 CARB-Q is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 427 MPa (61.9 ksi) for 1016-CD, about 12% more; tensile strength follows at 690 MPa (100 ksi) vs 483 MPa (70.1 ksi). In exchange, 1016-CD is the more ductile: elongation 18% versus 15% for 1016 CARB-Q, and 1016 CARB-Q is harder (200 HB vs 143 HB). 1016-CD runs hotter in service (400°C vs 180°C continuous). On the shop floor, 1016-CD machines more easily (good vs poor) and 1016-CD welds better (excellent vs poor).
1016 CARB-QChoose it when strength drives the design.
1016-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1016 CARB-Q vs 1016-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.

1016 CARB-Q vs 1016-CD — frequently asked
Is 1016 CARB-Q stronger than 1016-CD?
Yes. 1016 CARB-Q has a typical yield strength of 480 MPa (69.6 ksi) against 427 MPa (61.9 ksi) for 1016-CD — about 12% more. Tensile strength is 690 MPa (100 ksi) vs 483 MPa (70.1 ksi).
Which condition does FabDigit quote by default, CARB-Q or CD?
CD is the default 1016 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, 1016 CARB-Q or 1016-CD?
1016-CD. Its machinability rates good (62/100) against poor (15/100) for 1016 CARB-Q; for welding the order is 1016-CD first (excellent, 90/100) then 1016 CARB-Q (poor, 30/100).
