Steel DP1180 vs DP600
Steel · grade comparison
Steel DP1180 and DP600 are both steel grades. DP1180 is the stronger of the two: yield strength 950 MPa (138 ksi) against 380 MPa (55.1 ksi) for DP600, about 150% more; tensile strength follows at 1,230 MPa (178 ksi) vs 640 MPa (92.8 ksi). In exchange, DP600 is the more ductile: elongation 24% versus 7% for DP1180, and DP1180 is harder (360 HB vs 190 HB). DP600 conducts heat better (46 W/m·K vs 34 W/m·K). On the shop floor, DP600 machines more easily (fair vs poor).
DP1180Choose it when strength drives the design.
DP600Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
DP1180 vs DP600: 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.

DP1180 vs DP600 — frequently asked
Is DP1180 stronger than DP600?
Yes. DP1180 has a typical yield strength of 950 MPa (138 ksi) against 380 MPa (55.1 ksi) for DP600 — about 150% more. Tensile strength is 1,230 MPa (178 ksi) vs 640 MPa (92.8 ksi).
Which is cheaper, DP1180 or DP600?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, DP1180 or DP600?
DP600. Its machinability rates fair (45/100) against poor (28/100) for DP1180; for welding the order is DP600 first (very good, 72/100) then DP1180 (good, 65/100).
