Steel 18Ni(200) Maraging Steel vs AF1410
Steel · grade comparison
Steel 18Ni(200) Maraging Steel and AF1410 are both steel grades. AF1410 is the stronger of the two: yield strength 1,520 MPa (220 ksi) against 1,400 MPa (203 ksi) for 18Ni(200) Maraging Steel, about 9% more; tensile strength follows at 1,660 MPa (241 ksi) vs 1,450 MPa (210 ksi). AF1410 is the more ductile: elongation 16% versus 12% for 18Ni(200) Maraging Steel, and AF1410 is harder (48 HRC vs 43 HRC). AF1410 is stiffer (196 GPa vs 186 GPa) and AF1410 conducts heat better (24 W/m·K vs 20.5 W/m·K). On the shop floor, 18Ni(200) Maraging Steel welds better (very good vs good).

18Ni(200) Maraging Steel vs AF1410: 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.

18Ni(200) Maraging Steel vs AF1410 — frequently asked
Is AF1410 stronger than 18Ni(200) Maraging Steel?
Yes. AF1410 has a typical yield strength of 1,520 MPa (220 ksi) against 1,400 MPa (203 ksi) for 18Ni(200) Maraging Steel — about 9% more. Tensile strength is 1,660 MPa (241 ksi) vs 1,450 MPa (210 ksi).
Which is cheaper, 18Ni(200) Maraging Steel or AF1410?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 18Ni(200) Maraging Steel or AF1410?
18Ni(200) Maraging Steel, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for AF1410; for welding the order is 18Ni(200) Maraging Steel first (very good, 70/100) then AF1410 (good, 60/100).
