Stainless Steel 420V vs Nitronic 60
Stainless Steel · grade comparison
Stainless Steel 420V and Nitronic 60 are both stainless steel grades, both wear resistant ss. 420V is the stronger of the two: yield strength 600 MPa (87 ksi) against 414 MPa (60 ksi) for Nitronic 60, about 45% more; tensile strength follows at 900 MPa (131 ksi) vs 717 MPa (104 ksi). In exchange, Nitronic 60 is the more ductile: elongation 60% versus 8% for 420V, and 420V is harder (255 HB vs 210 HB). 420V is lighter (7.39 g/cm³ vs 7.63 g/cm³ for Nitronic 60) and 420V is stiffer (210 GPa vs 196 GPa). On the shop floor, Nitronic 60 machines more easily (28 vs 15 out of 100) and Nitronic 60 welds better (very good vs not recommended).
420VChoose it when strength drives the design, or when weight is the constraint.
Nitronic 60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
420V vs Nitronic 60: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless 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.

420V vs Nitronic 60 — frequently asked
Is 420V stronger than Nitronic 60?
Yes. 420V has a typical yield strength of 600 MPa (87 ksi) against 414 MPa (60 ksi) for Nitronic 60 — about 45% more. Tensile strength is 900 MPa (131 ksi) vs 717 MPa (104 ksi).
Which is cheaper, 420V or Nitronic 60?
Both sit in the same relative cost tier ($$$$$, specialty); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 420V or Nitronic 60?
Nitronic 60, by a small margin. Both rate poor for machinability — 28/100 against 15/100 for 420V; for welding the order is Nitronic 60 first (very good, 72/100) then 420V (not recommended, 12/100).
