Steel Creusabro 4000 vs Dillidur 400V
Steel · grade comparison
Steel Creusabro 4000 and Dillidur 400V are both steel grades. Dillidur 400V is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 1,000 MPa (145 ksi) for Creusabro 4000, about 10% more. In exchange, Creusabro 4000 is the more ductile: elongation 12% versus 10% for Dillidur 400V. Creusabro 4000 runs hotter in service (400°C vs 250°C continuous). On the shop floor, Dillidur 400V sits in a lower cost tier (budget, $) than Creusabro 4000 (standard, $$).
Creusabro 4000Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Dillidur 400VChoose it when strength drives the design, or when cost is the deciding factor.
Creusabro 4000 vs Dillidur 400V: 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.
