Steel 4817 vs 5160

Steel · grade comparison

Steel 4817 and 5160 are both steel grades. 4817 is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 275 MPa (39.9 ksi) for 5160, about 64% more. 4817 is the more ductile: elongation 24% versus 17% for 5160. 5160 runs hotter in service (250°C vs 200°C continuous) and 5160 conducts heat better (46 W/m·K vs 33 W/m·K). On the shop floor, 5160 machines more easily (good vs fair), 4817 welds better (fair vs poor), and 4817 sits in a lower cost tier (standard, $$) than 5160 (premium, $$$).

4817Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

5160Choose it when the part sees heat, or when the part is machined in volume.
