Steel X82WMoCrV6-5-4-A vs X82WMoCrV6-5-4 CD-A
Steel · X82WMoCrV6-5-4 temper comparison
X82WMoCrV6-5-4-A and X82WMoCrV6-5-4 CD-A are two conditions of the same steel grade, X82WMoCrV6-5-4: A (solution annealed) versus CD-A (cold drawn / ground annealed bar). The chemistry is identical, so every difference below comes from the condition. X82WMoCrV6-5-4 CD-A is the stronger of the two: yield strength 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for X82WMoCrV6-5-4-A, about 27% more; tensile strength follows at 950 MPa (138 ksi) vs 880 MPa (128 ksi). In exchange, X82WMoCrV6-5-4-A is the more ductile: elongation 12% versus 8% for X82WMoCrV6-5-4 CD-A, and X82WMoCrV6-5-4 CD-A is harder (265 HB vs 250 HB).
X82WMoCrV6-5-4-AChoose it when the part is bent, formed or impact-loaded.
X82WMoCrV6-5-4 CD-AChoose it when strength drives the design.
X82WMoCrV6-5-4-A vs X82WMoCrV6-5-4 CD-A: 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.
