Steel 60# Annealed vs 60#-HR

Steel · 60# temper comparison

60# Annealed and 60#-HR are two conditions of the same steel grade, 60#: Annealed versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 60#-HR is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 380 MPa (55.1 ksi) for 60# Annealed, about 11% more; tensile strength follows at 750 MPa (109 ksi) vs 660 MPa (95.7 ksi). In exchange, 60# Annealed is the more ductile: elongation 22% versus 17% for 60#-HR, and 60#-HR is harder (235 HB vs 190 HB).

60# AnnealedChoose it when the part is bent, formed or impact-loaded.

60#-HRChoose it when strength drives the design.
