Steel 5130 vs 5160

Steel · grade comparison

Steel 5130 and 5160 are both steel grades. 5130 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 275 MPa (39.9 ksi) for 5160, about 51% more. 5130 is the more ductile: elongation 22% versus 17% for 5160, and 5160 is harder (197 HB vs 187 HB). 5130 runs hotter in service (400°C vs 250°C continuous). On the shop floor, 5130 welds better (fair vs poor) and 5130 sits in a lower cost tier (standard, $$) than 5160 (premium, $$$).
