Steel 4Cr5MoSiV1 vs H13
Steel · grade comparison
Steel 4Cr5MoSiV1 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 4Cr5MoSiV1, about 13% more. H13 is the more ductile: elongation 25% versus 20% for 4Cr5MoSiV1. On the shop floor, 4Cr5MoSiV1 sits in a lower cost tier (standard, $$) than H13 (high, $$$$).
4Cr5MoSiV1Choose it when cost is the deciding factor.
H13Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
4Cr5MoSiV1 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.
