Steel S460M vs S700MC
Steel · grade comparison
Steel S460M and S700MC are both steel grades. S700MC is the stronger of the two: yield strength 740 MPa (107 ksi) against 490 MPa (71.1 ksi) for S460M, about 51% more; tensile strength follows at 810 MPa (117 ksi) vs 610 MPa (88.5 ksi). In exchange, S460M is the more ductile: elongation 24% versus 14% for S700MC, and S700MC is harder (245 HB vs 185 HB). S460M runs hotter in service (350°C vs 300°C continuous) and S460M conducts heat better (45 W/m·K vs 40 W/m·K). On the shop floor, S460M sits in a lower cost tier (budget, $) than S700MC (standard, $$).

S460M vs S700MC: 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.
