Steel 4024 vs 5160
Steel · grade comparison
Steel 4024 and 5160 are both steel grades. 4024 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 275 MPa (39.9 ksi) for 5160, about 20% more. 4024 is the more ductile: elongation 25% versus 17% for 5160, and 5160 is harder (197 HB vs 143 HB). 4024 runs hotter in service (400°C vs 250°C continuous). On the shop floor, 4024 machines more easily (very good vs good), 4024 welds better (fair vs poor), and 4024 sits in a lower cost tier (budget, $) than 5160 (premium, $$$).
4024Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
4024 vs 5160: 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.

4024 vs 5160 — frequently asked
Is 4024 stronger than 5160?
Yes. 4024 has a typical yield strength of 330 MPa (47.9 ksi) against 275 MPa (39.9 ksi) for 5160 — about 20% more. Tensile strength is 490 MPa (71.1 ksi) vs 725 MPa (105 ksi).
Which is cheaper, 4024 or 5160?
4024 is the lower-cost material: it sits in the budget tier ($) while 5160 is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 4024 or 5160?
4024. Its machinability rates very good (72/100) against good (55/100) for 5160; for welding the order is 4024 first (fair, 35/100) then 5160 (poor, 25/100).
