Steel EN-GJMW-400-5 Annealed vs EN-GJMW-400-5-d6
Steel · EN-GJMW-400-5 temper comparison
EN-GJMW-400-5 Annealed and EN-GJMW-400-5-d6 are two conditions of the same steel grade, EN-GJMW-400-5: Annealed versus d6 (annealed, 6 mm test bar). The chemistry is identical, so every difference below comes from the condition. EN-GJMW-400-5 Annealed is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 215 MPa (31.2 ksi) for EN-GJMW-400-5-d6, about 12% more; tensile strength follows at 430 MPa (62.4 ksi) vs 385 MPa (55.8 ksi). In exchange, EN-GJMW-400-5-d6 is the more ductile: elongation 10% versus 7% for EN-GJMW-400-5 Annealed, and EN-GJMW-400-5 Annealed is harder (195 HB vs 175 HB). On the shop floor, EN-GJMW-400-5-d6 welds better (very good vs good).

EN-GJMW-400-5 Annealed vs EN-GJMW-400-5-d6: 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.
