Steel T10A vs T8A
Steel · grade comparison
Steel T10A and T8A are both steel grades. T10A is the stronger of the two: yield strength 400 MPa (58 ksi) against 375 MPa (54.4 ksi) for T8A, about 7% more; tensile strength follows at 700 MPa (102 ksi) vs 620 MPa (89.9 ksi).
T10AChoose it when strength drives the design.
T10A vs T8A: 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.

T10A vs T8A — frequently asked
Is T10A stronger than T8A?
Yes. T10A has a typical yield strength of 400 MPa (58 ksi) against 375 MPa (54.4 ksi) for T8A — about 7% more. Tensile strength is 700 MPa (102 ksi) vs 620 MPa (89.9 ksi).
Which is cheaper, T10A or T8A?
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.
When should I choose T10A over T8A?
Pick T10A when strength drives the design.
