Steel 1117 vs Y45MnV
Steel · grade comparison
Steel 1117 and Y45MnV are both steel grades. Y45MnV is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 235 MPa (34.1 ksi) for 1117, about 138% more; tensile strength follows at 860 MPa (125 ksi) vs 425 MPa (61.6 ksi). In exchange, 1117 is the more ductile: elongation 33% versus 14% for Y45MnV, and Y45MnV is harder (255 HB vs 121 HB). 1117 conducts heat better (51 W/m·K vs 44 W/m·K). On the shop floor, 1117 welds better (fair vs poor).
1117Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
Y45MnVChoose it when strength drives the design.
1117 vs Y45MnV: 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.

1117 vs Y45MnV — frequently asked
Is Y45MnV stronger than 1117?
Yes. Y45MnV has a typical yield strength of 560 MPa (81.2 ksi) against 235 MPa (34.1 ksi) for 1117 — about 138% more. Tensile strength is 860 MPa (125 ksi) vs 425 MPa (61.6 ksi).
Which is cheaper, 1117 or Y45MnV?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1117 or Y45MnV?
1117. Its machinability rates very good (70/100) against good (62/100) for Y45MnV; for welding the order is 1117 first (fair, 50/100) then Y45MnV (poor, 22/100).
