Steel 2083 vs 420 Mod Mold
Steel · grade comparison
Steel 2083 and 420 Mod Mold are both steel grades, both mold steel. Both yield at about 480 MPa — strength does not separate them. 420 Mod Mold is the more ductile: elongation 19% versus 16% for 2083. 2083 is stiffer (215 GPa vs 200 GPa).

2083 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.

2083 vs 420 Mod Mold — frequently asked
What is the difference between 2083 and 420 Mod Mold?
Steel 2083 and 420 Mod Mold are both steel grades, both mold steel. Both yield at about 480 MPa — strength does not separate them. 420 Mod Mold is the more ductile: elongation 19% versus 16% for 2083.
Which is cheaper, 2083 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, 2083 or 420 Mod Mold?
420 Mod Mold, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 2083.
