Steel MS1700 vs QP1180
Steel · grade comparison
Steel MS1700 and QP1180 are both steel grades. MS1700 is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 920 MPa (133 ksi) for QP1180, about 58% more; tensile strength follows at 1,780 MPa (258 ksi) vs 1,240 MPa (180 ksi). In exchange, QP1180 is the more ductile: elongation 15% versus 4% for MS1700, and MS1700 is harder (50 HRC vs 39 HRC). MS1700 conducts heat better (32 W/m·K vs 28 W/m·K). On the shop floor, QP1180 sits in a lower cost tier (budget, $) than MS1700 (standard, $$).
MS1700Choose it when strength drives the design.
QP1180Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
MS1700 vs QP1180: 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.
