Steel W6Mo5Cr4V3-A vs W6Mo5Cr4V3-CDA
Steel · W6Mo5Cr4V3 temper comparison
W6Mo5Cr4V3-A and W6Mo5Cr4V3-CDA are two conditions of the same steel grade, W6Mo5Cr4V3: A (solution annealed) versus CDA (cold drawn / peeled annealed bar). The chemistry is identical, so every difference below comes from the condition. W6Mo5Cr4V3-CDA is the stronger of the two: yield strength 700 MPa (102 ksi) against 560 MPa (81.2 ksi) for W6Mo5Cr4V3-A, about 25% more; tensile strength follows at 950 MPa (138 ksi) vs 860 MPa (125 ksi). In exchange, W6Mo5Cr4V3-A is the more ductile: elongation 12% versus 8% for W6Mo5Cr4V3-CDA, and W6Mo5Cr4V3-CDA is harder (265 HB vs 248 HB). W6Mo5Cr4V3-CDA runs hotter in service (550°C vs 300°C continuous).
W6Mo5Cr4V3-AChoose it when the part is bent, formed or impact-loaded.
W6Mo5Cr4V3-CDAChoose it when strength drives the design, or when the part sees heat.
W6Mo5Cr4V3-A vs W6Mo5Cr4V3-CDA: 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.
