Steel H13 vs H19
Steel · grade comparison
Steel H13 and H19 are both steel grades. H19 is the stronger of the two: tensile strength 800 MPa (116 ksi) against 760 MPa (110 ksi) for H13, about 5% more. In exchange, H13 is the more ductile: elongation 25% versus 18% for H19, and H19 is harder (220 HB vs 205 HB). H13 is lighter (7.8 g/cm³ vs 8.19 g/cm³ for H19) and H13 conducts electricity better (3.3 % IACS vs 2.7 % IACS). On the shop floor, H13 machines more easily (45 vs 35 out of 100).
H13Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
H19Choose it when strength drives the design.
H13 vs H19: 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.

H13 vs H19 — frequently asked
Is H19 stronger than H13?
Yes. H19 has a typical tensile strength of 800 MPa (116 ksi) against 760 MPa (110 ksi) for H13 — about 5% more.
Which is cheaper, H13 or H19?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, H13 or H19?
H13, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for H19; for welding the order is H13 first (fair, 35/100) then H19 (poor, 30/100).
