Steel 3Cr2W8V vs H13
Steel · grade comparison
Steel 3Cr2W8V and H13 are both steel grades. H13 is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 460 MPa (66.7 ksi) for 3Cr2W8V, about 13% more. H13 is the more ductile: elongation 25% versus 18% for 3Cr2W8V, and 3Cr2W8V is harder (229 HB vs 205 HB). H13 is lighter (7.8 g/cm³ vs 8.3 g/cm³ for 3Cr2W8V). On the shop floor, H13 welds better (fair vs poor) and 3Cr2W8V sits in a lower cost tier (premium, $$$) than H13 (high, $$$$).
3Cr2W8VChoose it when cost is the deciding factor.
H13Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
3Cr2W8V 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.

3Cr2W8V vs H13 — frequently asked
Is H13 stronger than 3Cr2W8V?
Yes. H13 has a typical yield strength of 520 MPa (75.4 ksi) against 460 MPa (66.7 ksi) for 3Cr2W8V — about 13% more. Tensile strength is 760 MPa (110 ksi) vs 760 MPa (110 ksi).
Which is cheaper, 3Cr2W8V or H13?
3Cr2W8V 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, 3Cr2W8V or H13?
H13, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 3Cr2W8V; for welding the order is H13 first (fair, 35/100) then 3Cr2W8V (poor, 25/100).
