Steel 38MnVS6-HR vs 38MnVS6-N
Steel · 38MnVS6 temper comparison
38MnVS6-HR and 38MnVS6-N are two conditions of the same steel grade, 38MnVS6: HR (hot rolled) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 38MnVS6-HR is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 510 MPa (74 ksi) for 38MnVS6-N, about 12% more; tensile strength follows at 860 MPa (125 ksi) vs 810 MPa (117 ksi). In exchange, 38MnVS6-N is the more ductile: elongation 17% versus 15% for 38MnVS6-HR, and 38MnVS6-HR is harder (255 HB vs 240 HB).
38MnVS6-HRChoose it when strength drives the design.
38MnVS6-NChoose it when the part is bent, formed or impact-loaded.
38MnVS6-HR vs 38MnVS6-N: 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.

38MnVS6-HR vs 38MnVS6-N — frequently asked
Is 38MnVS6-HR stronger than 38MnVS6-N?
Yes. 38MnVS6-HR has a typical yield strength of 570 MPa (82.7 ksi) against 510 MPa (74 ksi) for 38MnVS6-N — about 12% more. Tensile strength is 860 MPa (125 ksi) vs 810 MPa (117 ksi).
Which condition does FabDigit quote by default, HR or N?
As Forged is the default 38MnVS6 condition in the FabDigit quote flow (neither HR nor N). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose 38MnVS6-HR over 38MnVS6-N?
Pick 38MnVS6-HR when strength drives the design. Pick 38MnVS6-N when the part is bent, formed or impact-loaded.
