Steel CRGO Annealed vs CRGO Cold Rolled
Steel · CRGO temper comparison
CRGO Annealed and CRGO Cold Rolled are two conditions of the same steel grade, CRGO: Annealed versus Cold Rolled. The chemistry is identical, so every difference below comes from the condition. CRGO Cold Rolled is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 305 MPa (44.2 ksi) for CRGO Annealed, about 87% more; tensile strength follows at 650 MPa (94.3 ksi) vs 345 MPa (50 ksi). In exchange, CRGO Annealed is the more ductile: elongation 10% versus 3% for CRGO Cold Rolled, and CRGO Cold Rolled is harder (255 HB vs 170 HB). CRGO Annealed runs hotter in service (200°C vs 150°C continuous). On the shop floor, CRGO Annealed machines more easily (45 vs 35 out of 100).
CRGO AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
CRGO Cold RolledChoose it when strength drives the design.
CRGO Annealed vs CRGO Cold Rolled: 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.

CRGO Annealed vs CRGO Cold Rolled — frequently asked
Is CRGO Cold Rolled stronger than CRGO Annealed?
Yes. CRGO Cold Rolled has a typical yield strength of 570 MPa (82.7 ksi) against 305 MPa (44.2 ksi) for CRGO Annealed — about 87% more. Tensile strength is 650 MPa (94.3 ksi) vs 345 MPa (50 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Rolled?
Annealed is the default CRGO 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, CRGO Annealed or CRGO Cold Rolled?
CRGO Annealed, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for CRGO Cold Rolled; for welding the order is CRGO Annealed first (poor, 30/100) then CRGO Cold Rolled (poor, 25/100).
