Steel A514 vs EN36

Steel · grade comparison

Steel A514 and EN36 are both steel grades. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 450 MPa (65.3 ksi) for EN36, about 69% more; tensile strength follows at 800 MPa (116 ksi) vs 700 MPa (102 ksi). A514 is harder — 250 HB against 200 HB for EN36 — which matters for wear surfaces and threads. A514 runs hotter in service (400°C vs 250°C continuous) and A514 conducts heat better (42 W/m·K vs 36 W/m·K). On the shop floor, A514 welds better (good vs poor) and EN36 forms better (fair vs poor).

A514Choose it when strength drives the design, or when surface hardness matters.

A514 vs EN36 — frequently asked

Is A514 stronger than EN36?

Yes. A514 has a typical yield strength of 760 MPa (110 ksi) against 450 MPa (65.3 ksi) for EN36 — about 69% more. Tensile strength is 800 MPa (116 ksi) vs 700 MPa (102 ksi).

Which is cheaper, A514 or EN36?

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 EN36?

EN36, 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 EN36 (poor, 30/100).
