Steel 8407 vs H13
Steel · grade comparison
Steel 8407 and H13 are both steel grades. 8407 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 8407, and H13 is harder (205 HB vs 180 HB). 8407 runs hotter in service (540°C vs 400°C continuous). On the shop floor, 8407 machines more easily (good vs fair), 8407 welds better (45 vs 35 out of 100), and 8407 sits in a lower cost tier (premium, $$$) than H13 (high, $$$$).
8407Choose it when strength drives the design, or when the part sees heat.
H13Choose it when the part is bent, formed or impact-loaded.
8407 vs H13: 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.

8407 vs H13 — frequently asked
Is 8407 stronger than H13?
Yes. 8407 has a typical tensile strength of 800 MPa (116 ksi) against 760 MPa (110 ksi) for H13 — about 5% more.
Which is cheaper, 8407 or H13?
8407 is the lower-cost material: it sits in the premium tier ($$$) while H13 is high ($$$$). 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, 8407 or H13?
8407. Its machinability rates good (55/100) against fair (45/100) for H13; for welding the order is 8407 first (fair, 45/100) then H13 (fair, 35/100).
