Steel EN-GJMW-400-5 Annealed vs EN-GJMW-400-5-D15
Steel · EN-GJMW-400-5 temper comparison
EN-GJMW-400-5 Annealed and EN-GJMW-400-5-D15 are two conditions of the same steel grade, EN-GJMW-400-5: Annealed versus D15 (annealed, 15 mm test bar). The chemistry is identical, so every difference below comes from the condition. Both yield at about 240 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus annealed, 15 mm test bar). EN-GJMW-400-5 Annealed is the more ductile: elongation 7% versus 5% for EN-GJMW-400-5-D15.

EN-GJMW-400-5 Annealed vs EN-GJMW-400-5-D15: 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.
