Steel T10A vs T13A
Steel · grade comparison
Steel T10A and T13A are both steel grades. Both yield at about 400 MPa — strength does not separate them. T10A is the more ductile: elongation 22% versus 18% for T13A, and T13A is harder (197 HB vs 187 HB). On the shop floor, T10A machines more easily (good vs fair).
T10AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
T10A vs T13A: 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 T13A — frequently asked
What is the difference between T10A and T13A?
Steel T10A and T13A are both steel grades. Both yield at about 400 MPa — strength does not separate them. T10A is the more ductile: elongation 22% versus 18% for T13A, and T13A is harder (197 HB vs 187 HB).
Which is cheaper, T10A or T13A?
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, T10A or T13A?
T10A. Its machinability rates good (55/100) against fair (40/100) for T13A.
