Steel A514 vs EN24T

Steel · grade comparison

Steel A514 and EN24T are both steel grades, both high strength steel. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 560 MPa (81.2 ksi) for EN24T, about 36% more. A514 is the more ductile: elongation 19% versus 16% for EN24T, and EN24T is harder (265 HB vs 250 HB). EN24T conducts electricity better (7.8 % IACS vs 7 % IACS). On the shop floor, A514 welds better (good vs poor).

A514Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

A514 vs EN24T — frequently asked

Is A514 stronger than EN24T?

Yes. A514 has a typical yield strength of 760 MPa (110 ksi) against 560 MPa (81.2 ksi) for EN24T — about 36% more. Tensile strength is 800 MPa (116 ksi) vs 900 MPa (131 ksi).

Which is cheaper, A514 or EN24T?

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, A514 or EN24T?

EN24T, by a small margin. Both rate fair for machinability — 46/100 against 38/100 for A514; for welding the order is A514 first (good, 55/100) then EN24T (poor, 30/100).
