Steel X82WMoCrV6-5-4-A vs X82WMoCrV6-5-4-HT60
Steel · X82WMoCrV6-5-4 temper comparison
X82WMoCrV6-5-4-A and X82WMoCrV6-5-4-HT60 are two conditions of the same steel grade, X82WMoCrV6-5-4: A (solution annealed) versus HT60 (HT 60–62 HRC). The chemistry is identical, so every difference below comes from the condition. X82WMoCrV6-5-4-HT60 is the stronger of the two: yield strength 2,000 MPa (290 ksi) against 550 MPa (79.8 ksi) for X82WMoCrV6-5-4-A, about 3.6 times as much; tensile strength follows at 2,300 MPa (334 ksi) vs 880 MPa (128 ksi). In exchange, X82WMoCrV6-5-4-A is the more ductile: elongation 12% versus 1% for X82WMoCrV6-5-4-HT60, and X82WMoCrV6-5-4-HT60 is harder (745 HV vs 262 HV). X82WMoCrV6-5-4-HT60 runs hotter in service (450°C vs 300°C continuous). On the shop floor, X82WMoCrV6-5-4-A machines more easily (fair vs not recommended).
X82WMoCrV6-5-4-AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
X82WMoCrV6-5-4-HT60Choose it when strength drives the design, or when the part sees heat.
X82WMoCrV6-5-4-A vs X82WMoCrV6-5-4-HT60: 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.
