Steel 1.2344 vs 1.2714

Steel · grade comparison

Steel 1.2344 and 1.2714 are both steel grades, both mold steel. 1.2714 is the stronger of the two: yield strength 850 MPa (123 ksi) against 500 MPa (72.5 ksi) for 1.2344, about 70% more; tensile strength follows at 1,000 MPa (145 ksi) vs 800 MPa (116 ksi). In exchange, 1.2344 is the more ductile: elongation 20% versus 13% for 1.2714, and 1.2714 is harder (295 HB vs 215 HB). 1.2714 runs hotter in service (500°C vs 400°C continuous) and 1.2714 conducts heat better (34 W/m·K vs 24.5 W/m·K). On the shop floor, 1.2344 welds better (fair vs poor).

1.2344Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

1.2714Choose it when strength drives the design, or when the part sees heat.

1.2344 vs 1.2714 — frequently asked

Is 1.2714 stronger than 1.2344?

Yes. 1.2714 has a typical yield strength of 850 MPa (123 ksi) against 500 MPa (72.5 ksi) for 1.2344 — about 70% more. Tensile strength is 1,000 MPa (145 ksi) vs 800 MPa (116 ksi).

Which is cheaper, 1.2344 or 1.2714?

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 1.2714?

1.2714, 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 1.2714 (poor, 25/100).
