Steel Q460 vs X52
Steel · grade comparison
Steel Q460 and X52 are both steel grades. Q460 is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 415 MPa (60.2 ksi) for X52, about 20% more; tensile strength follows at 620 MPa (89.9 ksi) vs 530 MPa (76.9 ksi). In exchange, X52 is the more ductile: elongation 30% versus 21% for Q460, and Q460 is harder (185 HB vs 165 HB). X52 conducts electricity better (10 % IACS vs 8.2 % IACS). On the shop floor, X52 welds better (excellent vs very good).
Q460Choose it when strength drives the design.
X52Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
Q460 vs X52: 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.

Q460 vs X52 — frequently asked
Is Q460 stronger than X52?
Yes. Q460 has a typical yield strength of 500 MPa (72.5 ksi) against 415 MPa (60.2 ksi) for X52 — about 20% more. Tensile strength is 620 MPa (89.9 ksi) vs 530 MPa (76.9 ksi).
Which is cheaper, Q460 or X52?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Q460 or X52?
X52. Its machinability rates good (58/100) against fair (52/100) for Q460; for welding the order is X52 first (excellent, 92/100) then Q460 (very good, 70/100).
