Steel 1110 CARB vs 1110-CD
Steel · 1110 temper comparison
1110 CARB and 1110-CD are two conditions of the same steel grade, 1110: CARB (carburized and quenched, case ~0.5 mm) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1110-CD is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 350 MPa (50.8 ksi) for 1110 CARB, about 9% more. 1110-CD is the more ductile: elongation 15% versus 12% for 1110 CARB, and 1110 CARB is harder (130 HB vs 121 HB). On the shop floor, 1110-CD machines more easily (very good vs poor) and 1110-CD welds better (fair vs poor).
1110-CDChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1110 CARB vs 1110-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.

1110 CARB vs 1110-CD — frequently asked
Is 1110-CD stronger than 1110 CARB?
Yes. 1110-CD has a typical yield strength of 380 MPa (55.1 ksi) against 350 MPa (50.8 ksi) for 1110 CARB — about 9% more. Tensile strength is 440 MPa (63.8 ksi) vs 550 MPa (79.8 ksi).
Which condition does FabDigit quote by default, CARB or CD?
CD is the default 1110 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, 1110 CARB or 1110-CD?
1110-CD. Its machinability rates very good (78/100) against poor (20/100) for 1110 CARB; for welding the order is 1110-CD first (fair, 45/100) then 1110 CARB (poor, 20/100).
