Steel 50CrV4 Normalized vs 50CrV4 Q&T
Steel · 50CrV4 temper comparison
50CrV4 Normalized and 50CrV4 Q&T are two conditions of the same steel grade, 50CrV4: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 50CrV4 Q&T is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 600 MPa (87 ksi) for 50CrV4 Normalized, about 75% more; tensile strength follows at 1,250 MPa (181 ksi) vs 950 MPa (138 ksi). In exchange, 50CrV4 Normalized is the more ductile: elongation 13% versus 10% for 50CrV4 Q&T, and 50CrV4 Q&T is harder (375 HB vs 285 HB). 50CrV4 Q&T runs hotter in service (350°C vs 250°C continuous). On the shop floor, 50CrV4 Normalized welds better (25 vs 15 out of 100).
50CrV4 NormalizedChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
50CrV4 Q&TChoose it when strength drives the design, or when the part sees heat.
50CrV4 Normalized vs 50CrV4 Q&T: 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.

50CrV4 Normalized vs 50CrV4 Q&T — frequently asked
Is 50CrV4 Q&T stronger than 50CrV4 Normalized?
Yes. 50CrV4 Q&T has a typical yield strength of 1,050 MPa (152 ksi) against 600 MPa (87 ksi) for 50CrV4 Normalized — about 75% more. Tensile strength is 1,250 MPa (181 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, Normalized or Q&T?
Annealed is the default 50CrV4 condition in the FabDigit quote flow (neither Normalized nor Q&T). 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, 50CrV4 Normalized or 50CrV4 Q&T?
50CrV4 Normalized, by a small margin. Both rate fair for machinability — 46/100 against 38/100 for 50CrV4 Q&T; for welding the order is 50CrV4 Normalized first (poor, 25/100) then 50CrV4 Q&T (poor, 15/100).
