Steel A182 F36-ANN vs A182 F36-CL1
Steel · A182 F36 temper comparison
A182 F36-ANN and A182 F36-CL1 are two conditions of the same steel grade, A182 F36: ANN (annealed) versus CL1 (class 1). The chemistry is identical, so every difference below comes from the condition. A182 F36-CL1 is the stronger of the two: yield strength 465 MPa (67.4 ksi) against 350 MPa (50.8 ksi) for A182 F36-ANN, about 33% more; tensile strength follows at 620 MPa (89.9 ksi) vs 540 MPa (78.3 ksi). In exchange, A182 F36-ANN is the more ductile: elongation 30% versus 25% for A182 F36-CL1, and A182 F36-CL1 is harder (180 HB vs 150 HB).

A182 F36-ANN vs A182 F36-CL1: 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.

A182 F36-ANN vs A182 F36-CL1 — frequently asked
Is A182 F36-CL1 stronger than A182 F36-ANN?
Yes. A182 F36-CL1 has a typical yield strength of 465 MPa (67.4 ksi) against 350 MPa (50.8 ksi) for A182 F36-ANN — about 33% more. Tensile strength is 620 MPa (89.9 ksi) vs 540 MPa (78.3 ksi).
Which condition does FabDigit quote by default, ANN or CL1?
CL2 is the default A182 F36 condition in the FabDigit quote flow (neither ANN nor CL1). 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, A182 F36-ANN or A182 F36-CL1?
A182 F36-ANN, by a small margin. Both rate good for machinability — 68/100 against 62/100 for A182 F36-CL1.
