Steel 2316 vs 420 Mod Mold
Steel · grade comparison
Steel 2316 and 420 Mod Mold are both steel grades, both mold steel. 2316 is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 470 MPa (68.2 ksi) for 420 Mod Mold, about 11% more. 2316 is harder — 235 HB against 220 HB for 420 Mod Mold — which matters for wear surfaces and threads. 2316 is stiffer (215 GPa vs 200 GPa) and 420 Mod Mold conducts heat better (24 W/m·K vs 20 W/m·K). On the shop floor, 420 Mod Mold forms better (fair vs poor).
2316Choose it when strength drives the design, or when surface hardness matters.
2316 vs 420 Mod Mold: 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.

2316 vs 420 Mod Mold — frequently asked
Is 2316 stronger than 420 Mod Mold?
Yes. 2316 has a typical yield strength of 520 MPa (75.4 ksi) against 470 MPa (68.2 ksi) for 420 Mod Mold — about 11% more. Tensile strength is 780 MPa (113 ksi) vs 760 MPa (110 ksi).
Which is cheaper, 2316 or 420 Mod Mold?
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, 2316 or 420 Mod Mold?
2316, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 420 Mod Mold; for welding the order is 2316 first (poor, 30/100) then 420 Mod Mold (poor, 25/100).
