Steel A653-A60 vs A653-HR

Steel · A653 temper comparison

A653-A60 and A653-HR are two conditions of the same steel grade, A653: A60 versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. A653-HR is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 235 MPa (34.1 ksi) for A653-A60, about 11% more; tensile strength follows at 360 MPa (52.2 ksi) vs 330 MPa (47.9 ksi). In exchange, A653-A60 is the more ductile: elongation 36% versus 32% for A653-HR, and A653-HR is harder (110 HB vs 100 HB). A653-A60 runs hotter in service (230°C vs 200°C continuous). On the shop floor, A653-A60 welds better (82 vs 72 out of 100).

A653-A60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
