Steel DP1180 vs MS1700
Steel · grade comparison
Steel DP1180 and MS1700 are both steel grades. MS1700 is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 950 MPa (138 ksi) for DP1180, about 53% more; tensile strength follows at 1,780 MPa (258 ksi) vs 1,230 MPa (178 ksi). In exchange, DP1180 is the more ductile: elongation 7% versus 4% for MS1700, and MS1700 is harder (50 HRC vs 38 HRC). On the shop floor, DP1180 welds better (65 vs 55 out of 100) and DP1180 sits in a lower cost tier (budget, $) than MS1700 (standard, $$).
DP1180Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
MS1700Choose it when strength drives the design.
DP1180 vs MS1700: 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 MS1700 — frequently asked
Is MS1700 stronger than DP1180?
Yes. MS1700 has a typical yield strength of 1,450 MPa (210 ksi) against 950 MPa (138 ksi) for DP1180 — about 53% more. Tensile strength is 1,780 MPa (258 ksi) vs 1,230 MPa (178 ksi).
Which is cheaper, DP1180 or MS1700?
DP1180 is the lower-cost material: it sits in the budget tier ($) while MS1700 is standard ($$). 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, DP1180 or MS1700?
DP1180, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for MS1700; for welding the order is DP1180 first (good, 65/100) then MS1700 (good, 55/100).
