Steel 2083 vs 718H

Steel · grade comparison

Steel 2083 and 718H are both steel grades, both mold steel. 718H is the stronger of the two: yield strength 900 MPa (131 ksi) against 480 MPa (69.6 ksi) for 2083, about 88% more; tensile strength follows at 1,080 MPa (157 ksi) vs 760 MPa (110 ksi). In exchange, 2083 is the more ductile: elongation 16% versus 13% for 718H, and 718H is harder (300 HB vs 230 HB). 718H runs hotter in service (450°C vs 400°C continuous) and 718H conducts heat better (33 W/m·K vs 25 W/m·K). On the shop floor, 718H welds better (fair vs poor).

2083Choose it when the part is bent, formed or impact-loaded.

718HChoose it when strength drives the design, or when the part sees heat.

2083 vs 718H — frequently asked

Is 718H stronger than 2083?

Yes. 718H has a typical yield strength of 900 MPa (131 ksi) against 480 MPa (69.6 ksi) for 2083 — about 88% more. Tensile strength is 1,080 MPa (157 ksi) vs 760 MPa (110 ksi).

Which is cheaper, 2083 or 718H?

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 718H?

718H, by a small margin. Both rate fair for machinability — 48/100 against 40/100 for 2083; for welding the order is 718H first (fair, 40/100) then 2083 (poor, 25/100).
