Steel 2083 vs P20
Steel · grade comparison
Steel 2083 and P20 are both steel grades, both mold steel. 2083 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 440 MPa (63.8 ksi) for P20, about 9% more; tensile strength follows at 760 MPa (110 ksi) vs 700 MPa (102 ksi). In exchange, P20 is the more ductile: elongation 20% versus 16% for 2083, and 2083 is harder (230 HB vs 200 HB). P20 runs hotter in service (450°C vs 400°C continuous) and P20 conducts heat better (32 W/m·K vs 25 W/m·K). On the shop floor, P20 machines more easily (good vs fair), P20 welds better (fair vs poor), and 2083 sits in a lower cost tier (standard, $$) than P20 (specialty, $$$$$).
2083Choose it when strength drives the design, or when cost is the deciding factor.
P20Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
2083 vs P20: 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 P20 — frequently asked
Is 2083 stronger than P20?
Yes. 2083 has a typical yield strength of 480 MPa (69.6 ksi) against 440 MPa (63.8 ksi) for P20 — about 9% more. Tensile strength is 760 MPa (110 ksi) vs 700 MPa (102 ksi).
Which is cheaper, 2083 or P20?
2083 is the lower-cost material: it sits in the standard tier ($$) while P20 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 2083 or P20?
P20. Its machinability rates good (65/100) against fair (40/100) for 2083; for welding the order is P20 first (fair, 50/100) then 2083 (poor, 25/100).
