Steel 13MoCrNi42-16-14-ANN vs 13MoCrNi42-16-14 HT-CORE

Steel · 13MoCrNi42-16-14 temper comparison

13MoCrNi42-16-14-ANN and 13MoCrNi42-16-14 HT-CORE are two conditions of the same steel grade, 13MoCrNi42-16-14: ANN (annealed) versus HT-CORE (hardened & tempered (core condition, no carburizing) 43–48 HRC). The chemistry is identical, so every difference below comes from the condition. 13MoCrNi42-16-14 HT-CORE 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 13% for 13MoCrNi42-16-14 HT-CORE, and 13MoCrNi42-16-14 HT-CORE is harder (428 HB vs 220 HB). 13MoCrNi42-16-14 HT-CORE 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).
