Steel 1541 Annealed vs 1541-HR
Steel · 1541 temper comparison
1541 Annealed and 1541-HR are two conditions of the same steel grade, 1541: Annealed versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1541-HR is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 350 MPa (50.8 ksi) for 1541 Annealed, about 19% more; tensile strength follows at 700 MPa (102 ksi) vs 600 MPa (87 ksi). In exchange, 1541 Annealed is the more ductile: elongation 25% versus 15% for 1541-HR, and 1541-HR is harder (207 HB vs 170 HB).
1541 AnnealedChoose it when the part is bent, formed or impact-loaded.
1541-HRChoose it when strength drives the design.
1541 Annealed vs 1541-HR: 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.
