Stainless Steel L80-13Cr-ANN vs L80-13Cr QT-CPLG
Stainless Steel · L80-13Cr temper comparison
L80-13Cr-ANN and L80-13Cr QT-CPLG are two conditions of the same stainless steel grade, L80-13Cr: ANN (annealed) versus QT-CPLG (QT coupling stock). The chemistry is identical, so every difference below comes from the condition. L80-13Cr QT-CPLG is the stronger of the two: yield strength 610 MPa (88.5 ksi) against 320 MPa (46.4 ksi) for L80-13Cr-ANN, about 91% more; tensile strength follows at 720 MPa (104 ksi) vs 520 MPa (75.4 ksi). In exchange, L80-13Cr-ANN is the more ductile: elongation 28% versus 18% for L80-13Cr QT-CPLG, and L80-13Cr QT-CPLG is harder (235 HB vs 180 HB). On the shop floor, L80-13Cr-ANN machines more easily (52 vs 40 out of 100).
L80-13Cr-ANNChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
L80-13Cr QT-CPLGChoose it when strength drives the design.
L80-13Cr-ANN vs L80-13Cr QT-CPLG: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless 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.

L80-13Cr-ANN vs L80-13Cr QT-CPLG — frequently asked
Is L80-13Cr QT-CPLG stronger than L80-13Cr-ANN?
Yes. L80-13Cr QT-CPLG has a typical yield strength of 610 MPa (88.5 ksi) against 320 MPa (46.4 ksi) for L80-13Cr-ANN — about 91% more. Tensile strength is 720 MPa (104 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, ANN or QT-CPLG?
QT is the default L80-13Cr condition in the FabDigit quote flow (neither ANN nor QT-CPLG). 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, L80-13Cr-ANN or L80-13Cr QT-CPLG?
L80-13Cr-ANN, by a small margin. Both rate fair for machinability — 52/100 against 40/100 for L80-13Cr QT-CPLG.
