Steel EN-GJMW-400-5 Annealed vs EN-GJMW-400-5-AW
Steel · EN-GJMW-400-5 temper comparison
EN-GJMW-400-5 Annealed and EN-GJMW-400-5-AW are two conditions of the same steel grade, EN-GJMW-400-5: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. EN-GJMW-400-5 Annealed is the stronger of the two: tensile strength 430 MPa (62.4 ksi) against 380 MPa (55.1 ksi) for EN-GJMW-400-5-AW, about 13% more. EN-GJMW-400-5 Annealed is the more ductile: elongation 7% versus 4% for EN-GJMW-400-5-AW, and EN-GJMW-400-5-AW is harder (230 HB vs 195 HB). EN-GJMW-400-5 Annealed runs hotter in service (350°C vs 300°C continuous). On the shop floor, EN-GJMW-400-5 Annealed machines more easily (68 vs 58 out of 100).

EN-GJMW-400-5 Annealed vs EN-GJMW-400-5-AW: 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.
