Steel A514 vs En26

Steel · grade comparison

Steel A514 and En26 are both steel grades. En26 is the stronger of the two: tensile strength 930 MPa (135 ksi) against 800 MPa (116 ksi) for A514, about 16% more. In exchange, A514 is the more ductile: elongation 19% versus 16% for En26, and En26 is harder (277 HB vs 250 HB). On the shop floor, A514 welds better (good vs poor) and En26 sits in a lower cost tier (budget, $) than A514 (standard, $$).

A514Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

En26Choose it when strength drives the design, or when cost is the deciding factor.

A514 vs En26 — frequently asked

Is En26 stronger than A514?

Yes. En26 has a typical tensile strength of 930 MPa (135 ksi) against 800 MPa (116 ksi) for A514 — about 16% more.

Which is cheaper, A514 or En26?

En26 is the lower-cost material: it sits in the budget tier ($) while A514 is standard ($$). 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, A514 or En26?

En26, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for A514; for welding the order is A514 first (good, 55/100) then En26 (poor, 25/100).
