Steel W6Mo5Cr4V2 Annealed vs W6Mo5Cr4V2 Q&T 62-64 HRC
Steel · W6Mo5Cr4V2 temper comparison
W6Mo5Cr4V2 Annealed and W6Mo5Cr4V2 Q&T 62-64 HRC are two conditions of the same steel grade, W6Mo5Cr4V2: Annealed versus Q&T 62-64 HRC (hardened 1210–1230 °C, triple tempered ~550–560 °C). The chemistry is identical, so every difference below comes from the condition. W6Mo5Cr4V2 Q&T 62-64 HRC is the stronger of the two: tensile strength 2,300 MPa (334 ksi) against 850 MPa (123 ksi) for W6Mo5Cr4V2 Annealed, about 171% more. In exchange, W6Mo5Cr4V2 Annealed is the more ductile: elongation 12% versus 0.5% for W6Mo5Cr4V2 Q&T 62-64 HRC, and W6Mo5Cr4V2 Q&T 62-64 HRC is harder (63 HRC vs 23 HRC). W6Mo5Cr4V2 Q&T 62-64 HRC runs hotter in service (580°C vs 500°C continuous) and W6Mo5Cr4V2 Annealed conducts heat better (24 W/m·K vs 21 W/m·K). On the shop floor, W6Mo5Cr4V2 Annealed machines more easily (fair vs not recommended) and W6Mo5Cr4V2 Annealed welds better (poor vs not recommended).

W6Mo5Cr4V2 Annealed vs W6Mo5Cr4V2 Q&T 62-64 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.
