Steel Ingot Iron Full Hard vs Ingot Iron Hot Rolled
Steel · Ingot Iron temper comparison
Ingot Iron Full Hard and Ingot Iron Hot Rolled are two conditions of the same steel grade, Ingot Iron: Full Hard versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. Ingot Iron Full Hard is the stronger of the two: yield strength 410 MPa (59.5 ksi) against 185 MPa (26.8 ksi) for Ingot Iron Hot Rolled, about 122% more; tensile strength follows at 460 MPa (66.7 ksi) vs 310 MPa (45 ksi). In exchange, Ingot Iron Hot Rolled is the more ductile: elongation 35% versus 6% for Ingot Iron Full Hard, and Ingot Iron Full Hard is harder (135 HB vs 85 HB). Ingot Iron Hot Rolled runs hotter in service (450°C vs 250°C continuous). On the shop floor, Ingot Iron Hot Rolled welds better (95 vs 85 out of 100).
Ingot Iron Full HardChoose it when strength drives the design.
Ingot Iron Hot RolledChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ingot Iron Full Hard vs Ingot Iron Hot Rolled: 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.
