Steel A182 F1-A vs A182 F1 AS-FORGED
Steel · A182 F1 temper comparison
A182 F1-A and A182 F1 AS-FORGED are two conditions of the same steel grade, A182 F1: A (solution annealed) versus AS-FORGED (prior to final heat treatment). The chemistry is identical, so every difference below comes from the condition. A182 F1 AS-FORGED is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 300 MPa (43.5 ksi) for A182 F1-A, about 13% more; tensile strength follows at 560 MPa (81.2 ksi) vs 500 MPa (72.5 ksi). In exchange, A182 F1-A is the more ductile: elongation 31% versus 24% for A182 F1 AS-FORGED, and A182 F1 AS-FORGED is harder (175 HB vs 148 HB). A182 F1-A runs hotter in service (510°C vs 400°C continuous).

A182 F1-A vs A182 F1 AS-FORGED: 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 F1-A vs A182 F1 AS-FORGED — frequently asked
Is A182 F1 AS-FORGED stronger than A182 F1-A?
Yes. A182 F1 AS-FORGED has a typical yield strength of 340 MPa (49.3 ksi) against 300 MPa (43.5 ksi) for A182 F1-A — about 13% more. Tensile strength is 560 MPa (81.2 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, A or AS-FORGED?
N+T is the default A182 F1 condition in the FabDigit quote flow (neither A nor AS-FORGED). 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 F1-A or A182 F1 AS-FORGED?
A182 F1-A. Its machinability rates good (62/100) against fair (54/100) for A182 F1 AS-FORGED; for welding the order is A182 F1-A first (good, 68/100) then A182 F1 AS-FORGED (good, 60/100).
