Steel 1522 Annealed vs 1522 Q&T
Steel · 1522 temper comparison
1522 Annealed and 1522 Q&T are two conditions of the same steel grade, 1522: Annealed versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 1522 Q&T is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 275 MPa (39.9 ksi) for 1522 Annealed, about 75% more; tensile strength follows at 640 MPa (92.8 ksi) vs 460 MPa (66.7 ksi). In exchange, 1522 Annealed is the more ductile: elongation 27% versus 20% for 1522 Q&T, and 1522 Q&T is harder (190 HB vs 131 HB). On the shop floor, 1522 Annealed welds better (very good vs good).

1522 Annealed vs 1522 Q&T: 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.

1522 Annealed vs 1522 Q&T — frequently asked
Is 1522 Q&T stronger than 1522 Annealed?
Yes. 1522 Q&T has a typical yield strength of 480 MPa (69.6 ksi) against 275 MPa (39.9 ksi) for 1522 Annealed — about 75% more. Tensile strength is 640 MPa (92.8 ksi) vs 460 MPa (66.7 ksi).
Which condition does FabDigit quote by default, Annealed or Q&T?
HR is the default 1522 condition in the FabDigit quote flow (neither Annealed nor Q&T). 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 welds better, 1522 Annealed or 1522 Q&T?
1522 Annealed. Its weldability rates very good (78/100) against good (60/100) for 1522 Q&T.
