Steel 3310 Hot Rolled vs 3310 Spheroidize Annealed
Steel · 3310 temper comparison
3310 Hot Rolled and 3310 Spheroidize Annealed are two conditions of the same steel grade, 3310: Hot Rolled versus Spheroidize Annealed. The chemistry is identical, so every difference below comes from the condition. 3310 Hot Rolled is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 400 MPa (58 ksi) for 3310 Spheroidize Annealed, about 30% more; tensile strength follows at 780 MPa (113 ksi) vs 620 MPa (89.9 ksi). In exchange, 3310 Spheroidize Annealed is the more ductile: elongation 28% versus 20% for 3310 Hot Rolled, and 3310 Hot Rolled is harder (235 HB vs 170 HB). On the shop floor, 3310 Spheroidize Annealed machines more easily (fair vs poor).

3310 Hot Rolled 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.
