Steel H22-ANN vs H22-HR
Steel · H22 temper comparison
H22-ANN and H22-HR are two conditions of the same steel grade, H22: ANN (annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. H22-HR is the stronger of the two: yield strength 900 MPa (131 ksi) against 470 MPa (68.2 ksi) for H22-ANN, about 91% more; tensile strength follows at 1,150 MPa (167 ksi) vs 790 MPa (115 ksi). In exchange, H22-ANN is the more ductile: elongation 18% versus 10% for H22-HR, and H22-HR is harder (340 HB vs 212 HB). On the shop floor, H22-ANN machines more easily (32 vs 18 out of 100) and H22-ANN welds better (poor vs not recommended).
H22-ANNChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
H22-HRChoose it when strength drives the design.
H22-ANN vs H22-HR: 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.

H22-ANN vs H22-HR — frequently asked
Is H22-HR stronger than H22-ANN?
Yes. H22-HR has a typical yield strength of 900 MPa (131 ksi) against 470 MPa (68.2 ksi) for H22-ANN — about 91% more. Tensile strength is 1,150 MPa (167 ksi) vs 790 MPa (115 ksi).
Which condition does FabDigit quote by default, ANN or HR?
ANN is the default H22 condition in the FabDigit quote flow. 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, H22-ANN or H22-HR?
H22-ANN, by a small margin. Both rate poor for machinability — 32/100 against 18/100 for H22-HR; for welding the order is H22-ANN first (poor, 30/100) then H22-HR (not recommended, 12/100).
