Steel 1.2601 Annealed vs 1.2601 Q&T 60-62 HRC

Steel · 1.2601 temper comparison

1.2601 Annealed and 1.2601 Q&T 60-62 HRC are two conditions of the same steel grade, 1.2601: Annealed versus Q&T 60-62 HRC (hardened ~970 °C, tempered ~180–200 °C). The chemistry is identical, so every difference below comes from the condition. 1.2601 Q&T 60-62 HRC is the stronger of the two: tensile strength 2,250 MPa (326 ksi) against 800 MPa (116 ksi) for 1.2601 Annealed, about 181% more. 1.2601 Q&T 60-62 HRC is harder — 61 HRC against 20 HRC for 1.2601 Annealed — which matters for wear surfaces and threads. 1.2601 Annealed runs hotter in service (200°C vs 180°C continuous). On the shop floor, 1.2601 Annealed machines more easily (poor vs not recommended).
