Steel Creusabro 4000 vs Hardox 600
Steel · grade comparison
Steel Creusabro 4000 and Hardox 600 are both steel grades. Hardox 600 is the stronger of the two: yield strength 1,650 MPa (239 ksi) against 1,000 MPa (145 ksi) for Creusabro 4000, about 65% more; tensile strength follows at 2,000 MPa (290 ksi) vs 1,250 MPa (181 ksi). In exchange, Creusabro 4000 is the more ductile: elongation 12% versus 7% for Hardox 600, and Hardox 600 is harder (600 HB vs 400 HB). Creusabro 4000 runs hotter in service (400°C vs 250°C continuous) and Creusabro 4000 conducts heat better (36 W/m·K vs 30 W/m·K). On the shop floor, Creusabro 4000 machines more easily (poor vs not recommended) and Creusabro 4000 welds better (good vs poor).
Creusabro 4000Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Hardox 600Choose it when strength drives the design.
Creusabro 4000 vs Hardox 600: 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.

Creusabro 4000 vs Hardox 600 — frequently asked
Is Hardox 600 stronger than Creusabro 4000?
Yes. Hardox 600 has a typical yield strength of 1,650 MPa (239 ksi) against 1,000 MPa (145 ksi) for Creusabro 4000 — about 65% more. Tensile strength is 2,000 MPa (290 ksi) vs 1,250 MPa (181 ksi).
Which is cheaper, Creusabro 4000 or Hardox 600?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Creusabro 4000 or Hardox 600?
Creusabro 4000. Its machinability rates poor (25/100) against not recommended (8/100) for Hardox 600; for welding the order is Creusabro 4000 first (good, 60/100) then Hardox 600 (poor, 30/100).
