Steel MS1700 vs TRIP690
Steel · grade comparison
Steel MS1700 and TRIP690 are both steel grades. MS1700 is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 450 MPa (65.3 ksi) for TRIP690, about 3.2 times as much; tensile strength follows at 1,780 MPa (258 ksi) vs 720 MPa (104 ksi). In exchange, TRIP690 is the more ductile: elongation 26% versus 4% for MS1700, and MS1700 is harder (520 HV vs 220 HV). TRIP690 conducts heat better (45 W/m·K vs 32 W/m·K). On the shop floor, TRIP690 machines more easily (fair vs poor) and TRIP690 sits in a lower cost tier (budget, $) than MS1700 (standard, $$).
MS1700Choose it when strength drives the design.
TRIP690Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
MS1700 vs TRIP690: 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.
