Steel 17CrNiMo6 Annealed vs 17CrNiMo6 Normalized
Steel · 17CrNiMo6 temper comparison
17CrNiMo6 Annealed and 17CrNiMo6 Normalized are two conditions of the same steel grade, 17CrNiMo6: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. 17CrNiMo6 Normalized is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 430 MPa (62.4 ksi) for 17CrNiMo6 Annealed, about 30% more; tensile strength follows at 880 MPa (128 ksi) vs 700 MPa (102 ksi). In exchange, 17CrNiMo6 Annealed is the more ductile: elongation 20% versus 15% for 17CrNiMo6 Normalized, and 17CrNiMo6 Normalized is harder (260 HB vs 200 HB). 17CrNiMo6 Annealed runs hotter in service (300°C vs 200°C continuous).
17CrNiMo6 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
17CrNiMo6 NormalizedChoose it when strength drives the design.
17CrNiMo6 Annealed vs 17CrNiMo6 Normalized: 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.
