Steel A516 Gr 60-HR vs A516 Gr 60 Q&T
Steel · A516 Gr 60 temper comparison
A516 Gr 60-HR and A516 Gr 60 Q&T are two conditions of the same steel grade, A516 Gr 60: HR (hot rolled) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A516 Gr 60 Q&T is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 265 MPa (38.4 ksi) for A516 Gr 60-HR, about 40% more; tensile strength follows at 515 MPa (74.7 ksi) vs 460 MPa (66.7 ksi). A516 Gr 60 Q&T is harder — 160 HB against 130 HB for A516 Gr 60-HR — which matters for wear surfaces and threads.
A516 Gr 60 Q&TChoose it when strength drives the design, or when surface hardness matters.
A516 Gr 60-HR vs A516 Gr 60 Q&T: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
