Steel 5130 Annealed vs 5130-HR

Steel · 5130 temper comparison

5130 Annealed and 5130-HR are two conditions of the same steel grade, 5130: Annealed versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 5130-HR is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 380 MPa (55.1 ksi) for 5130 Annealed, about 9% more; tensile strength follows at 635 MPa (92.1 ksi) vs 590 MPa (85.6 ksi). In exchange, 5130 Annealed is the more ductile: elongation 26% versus 22% for 5130-HR, and 5130-HR is harder (187 HB vs 170 HB).
