Steel 1084 vs T10
Steel · grade comparison
Steel 1084 and T10 are both steel grades. 1084 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 420 MPa (60.9 ksi) for T10, about 39% more; tensile strength follows at 965 MPa (140 ksi) vs 720 MPa (104 ksi). In exchange, T10 is the more ductile: elongation 18% versus 12% for 1084, and 1084 is harder (293 HB vs 192 HB). 1084 runs hotter in service (400°C vs 300°C continuous). On the shop floor, T10 machines more easily (48 vs 35 out of 100) and 1084 sits in a lower cost tier (standard, $$) than T10 (premium, $$$).
1084Choose it when strength drives the design, or when the part sees heat.
T10Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1084 vs T10: 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.

1084 vs T10 — frequently asked
Is 1084 stronger than T10?
Yes. 1084 has a typical yield strength of 585 MPa (84.8 ksi) against 420 MPa (60.9 ksi) for T10 — about 39% more. Tensile strength is 965 MPa (140 ksi) vs 720 MPa (104 ksi).
Which is cheaper, 1084 or T10?
1084 is the lower-cost material: it sits in the standard tier ($$) while T10 is premium ($$$). 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, 1084 or T10?
T10, by a small margin. Both rate fair for machinability — 48/100 against 35/100 for 1084; for welding the order is 1084 first (poor, 20/100) then T10 (poor, 15/100).
