A1018 HSLAS-F Grade 50Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Q460Choose it when strength drives the design.
A1018 HSLAS-F Grade 50 vs Q460: 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.
