Steel 32CrAlMo7-10 +N vs 32CrAlMo7-10 +QT100-160
Steel · 32CrAlMo7-10 temper comparison
32CrAlMo7-10 +N and 32CrAlMo7-10 +QT100-160 are two conditions of the same steel grade, 32CrAlMo7-10: +N (normalized) versus +QT100-160 (+QT). The chemistry is identical, so every difference below comes from the condition. 32CrAlMo7-10 +QT100-160 is the stronger of the two: yield strength 700 MPa (102 ksi) against 560 MPa (81.2 ksi) for 32CrAlMo7-10 +N, about 25% more. In exchange, 32CrAlMo7-10 +N is the more ductile: elongation 15% versus 13% for 32CrAlMo7-10 +QT100-160, and 32CrAlMo7-10 +QT100-160 is harder (285 HB vs 270 HB). 32CrAlMo7-10 +QT100-160 runs hotter in service (500°C vs 450°C continuous).
32CrAlMo7-10 +NChoose it when the part is bent, formed or impact-loaded.
32CrAlMo7-10 +QT100-160Choose it when strength drives the design, or when the part sees heat.
32CrAlMo7-10 +N vs 32CrAlMo7-10 +QT100-160: 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.

32CrAlMo7-10 +N vs 32CrAlMo7-10 +QT100-160 — frequently asked
Is 32CrAlMo7-10 +QT100-160 stronger than 32CrAlMo7-10 +N?
Yes. 32CrAlMo7-10 +QT100-160 has a typical yield strength of 700 MPa (102 ksi) against 560 MPa (81.2 ksi) for 32CrAlMo7-10 +N — about 25% more. Tensile strength is 900 MPa (131 ksi) vs 880 MPa (128 ksi).
Which condition does FabDigit quote by default, +N or +QT100-160?
+QT is the default 32CrAlMo7-10 condition in the FabDigit quote flow (neither +N nor +QT100-160). 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.
When should I choose 32CrAlMo7-10 +N over 32CrAlMo7-10 +QT100-160?
Pick 32CrAlMo7-10 +N when the part is bent, formed or impact-loaded. Pick 32CrAlMo7-10 +QT100-160 when strength drives the design, or when the part sees heat.
