Steel 1.2344 vs 2316
Steel · grade comparison
Steel 1.2344 and 2316 are both steel grades, both mold steel. Both yield at about 500 MPa — strength does not separate them. 1.2344 is the more ductile: elongation 20% versus 18% for 2316, and 2316 is harder (235 HB vs 215 HB). 1.2344 conducts heat better (24.5 W/m·K vs 20 W/m·K).

1.2344 vs 2316: 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.

1.2344 vs 2316 — frequently asked
What is the difference between 1.2344 and 2316?
Steel 1.2344 and 2316 are both steel grades, both mold steel. Both yield at about 500 MPa — strength does not separate them. 1.2344 is the more ductile: elongation 20% versus 18% for 2316, and 2316 is harder (235 HB vs 215 HB).
Which is cheaper, 1.2344 or 2316?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1.2344 or 2316?
2316, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 1.2344; for welding the order is 1.2344 first (fair, 35/100) then 2316 (poor, 30/100).
