Steel 80MoCrV42-16-QT60 vs 80MoCrV42-16-QT62

Steel · 80MoCrV42-16 temper comparison

80MoCrV42-16-QT60 and 80MoCrV42-16-QT62 are two conditions of the same steel grade, 80MoCrV42-16: QT60 (QT 60-62 HRC) versus QT62 (QT 62-64 HRC). The chemistry is identical, so every difference below comes from the condition. 80MoCrV42-16-QT62 is the stronger of the two: tensile strength 2,550 MPa (370 ksi) against 2,400 MPa (348 ksi) for 80MoCrV42-16-QT60, about 6% more. In exchange, 80MoCrV42-16-QT60 is the more ductile: elongation 1.5% versus 1% for 80MoCrV42-16-QT62, and 80MoCrV42-16-QT62 is harder (790 HV vs 730 HV).
