Steel 6CrMnSi2Mo1V Normalized vs 6CrMnSi2Mo1V Q&T 54-56 HRC
Steel · 6CrMnSi2Mo1V temper comparison
6CrMnSi2Mo1V Normalized and 6CrMnSi2Mo1V Q&T 54-56 HRC are two conditions of the same steel grade, 6CrMnSi2Mo1V: Normalized versus Q&T 54-56 HRC (oil quench + temper ~250–300 °C). The chemistry is identical, so every difference below comes from the condition. 6CrMnSi2Mo1V Q&T 54-56 HRC is the stronger of the two: yield strength 1,650 MPa (239 ksi) against 800 MPa (116 ksi) for 6CrMnSi2Mo1V Normalized, about 106% more; tensile strength follows at 1,950 MPa (283 ksi) vs 1,150 MPa (167 ksi). In exchange, 6CrMnSi2Mo1V Normalized is the more ductile: elongation 10% versus 5% for 6CrMnSi2Mo1V Q&T 54-56 HRC, and 6CrMnSi2Mo1V Normalized is harder (340 HB vs 217 HB). 6CrMnSi2Mo1V Q&T 54-56 HRC runs hotter in service (230°C vs 200°C continuous). On the shop floor, 6CrMnSi2Mo1V Normalized machines more easily (poor vs not recommended).

6CrMnSi2Mo1V Normalized vs 6CrMnSi2Mo1V Q&T 54-56 HRC: 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.

6CrMnSi2Mo1V Normalized vs 6CrMnSi2Mo1V Q&T 54-56 HRC — frequently asked
Is 6CrMnSi2Mo1V Q&T 54-56 HRC stronger than 6CrMnSi2Mo1V Normalized?
Yes. 6CrMnSi2Mo1V Q&T 54-56 HRC has a typical yield strength of 1,650 MPa (239 ksi) against 800 MPa (116 ksi) for 6CrMnSi2Mo1V Normalized — about 106% more. Tensile strength is 1,950 MPa (283 ksi) vs 1,150 MPa (167 ksi).
Which condition does FabDigit quote by default, Normalized or Q&T 54-56 HRC?
Annealed is the default 6CrMnSi2Mo1V condition in the FabDigit quote flow (neither Normalized nor Q&T 54-56 HRC). 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.
Which is easier to machine, 6CrMnSi2Mo1V Normalized or 6CrMnSi2Mo1V Q&T 54-56 HRC?
6CrMnSi2Mo1V Normalized. Its machinability rates poor (30/100) against not recommended (10/100) for 6CrMnSi2Mo1V Q&T 54-56 HRC; for welding the order is 6CrMnSi2Mo1V Q&T 54-56 HRC first (poor, 20/100) then 6CrMnSi2Mo1V Normalized (poor, 15/100).
