Steel 3310 Cold Drawn vs 3310 Spheroidize Annealed
Steel · 3310 temper comparison
3310 Cold Drawn and 3310 Spheroidize Annealed are two conditions of the same steel grade, 3310: Cold Drawn versus Spheroidize Annealed. The chemistry is identical, so every difference below comes from the condition. 3310 Cold Drawn is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 400 MPa (58 ksi) for 3310 Spheroidize Annealed, about 63% more; tensile strength follows at 760 MPa (110 ksi) vs 620 MPa (89.9 ksi). In exchange, 3310 Spheroidize Annealed is the more ductile: elongation 28% versus 14% for 3310 Cold Drawn, and 3310 Cold Drawn is harder (225 HB vs 170 HB).

3310 Spheroidize AnnealedChoose it when the part is bent, formed or impact-loaded.
3310 Cold Drawn vs 3310 Spheroidize Annealed: 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.
