Steel 1.2363 Annealed vs 1.2363-ESR
Steel · 1.2363 temper comparison
1.2363 Annealed and 1.2363-ESR are two conditions of the same steel grade, 1.2363: Annealed versus ESR (electroslag remelted (premium cleanliness) bar/plate). The chemistry is identical, so every difference below comes from the condition. Both yield at about 500 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 electroslag remelted (premium cleanliness) bar/plate). 1.2363-ESR is the more ductile: elongation 18% versus 16% for 1.2363 Annealed. 1.2363 Annealed runs hotter in service (400°C vs 200°C continuous).

1.2363 Annealed vs 1.2363-ESR: 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.
