Steel 13MoCrNi42-16-14-ANN vs 13MoCrNi42-16-14 CARB-HT
Steel · 13MoCrNi42-16-14 temper comparison
13MoCrNi42-16-14-ANN and 13MoCrNi42-16-14 CARB-HT are two conditions of the same steel grade, 13MoCrNi42-16-14: ANN (annealed) versus CARB-HT (carburized, hardened, deep-frozen & tempered). The chemistry is identical, so every difference below comes from the condition. 13MoCrNi42-16-14 CARB-HT is the stronger of the two: yield strength 1,200 MPa (174 ksi) against 560 MPa (81.2 ksi) for 13MoCrNi42-16-14-ANN, about 114% more; tensile strength follows at 1,500 MPa (218 ksi) vs 860 MPa (125 ksi). In exchange, 13MoCrNi42-16-14-ANN is the more ductile: elongation 18% versus 12% for 13MoCrNi42-16-14 CARB-HT, and 13MoCrNi42-16-14 CARB-HT is harder (750 HV vs 232 HV). 13MoCrNi42-16-14 CARB-HT runs hotter in service (315°C vs 200°C continuous). On the shop floor, 13MoCrNi42-16-14-ANN machines more easily (poor vs not recommended) and 13MoCrNi42-16-14-ANN welds better (poor vs not recommended).
13MoCrNi42-16-14-ANNChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
13MoCrNi42-16-14 CARB-HTChoose it when strength drives the design, or when the part sees heat.
13MoCrNi42-16-14-ANN vs 13MoCrNi42-16-14 CARB-HT: 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.
