Steel 60CrMnA-HR vs 60CrMnA-QT

Steel · 60CrMnA temper comparison

60CrMnA-HR and 60CrMnA-QT are two conditions of the same steel grade, 60CrMnA: HR (hot rolled) versus QT (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 60CrMnA-QT is the stronger of the two: yield strength 1,180 MPa (171 ksi) against 600 MPa (87 ksi) for 60CrMnA-HR, about 97% more; tensile strength follows at 1,320 MPa (191 ksi) vs 950 MPa (138 ksi). In exchange, 60CrMnA-HR is the more ductile: elongation 14% versus 11% for 60CrMnA-QT, and 60CrMnA-QT is harder (390 HB vs 280 HB).
