Steel A232 vs A514

Steel · grade comparison

Steel A232 and A514 are both steel grades. A232 is the stronger of the two: yield strength 1,550 MPa (225 ksi) against 760 MPa (110 ksi) for A514, about 104% more; tensile strength follows at 1,750 MPa (254 ksi) vs 800 MPa (116 ksi). In exchange, A514 is the more ductile: elongation 19% versus 8% for A232, and A232 is harder (495 HB vs 250 HB). A514 runs hotter in service (400°C vs 230°C continuous). On the shop floor, A514 machines more easily (fair vs poor) and A514 welds better (good vs poor).

A232Choose it when strength drives the design.

A514Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

A232 vs A514 — frequently asked

Is A232 stronger than A514?

Yes. A232 has a typical yield strength of 1,550 MPa (225 ksi) against 760 MPa (110 ksi) for A514 — about 104% more. Tensile strength is 1,750 MPa (254 ksi) vs 800 MPa (116 ksi).

Which is cheaper, A232 or A514?

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, A232 or A514?

A514. Its machinability rates fair (38/100) against poor (20/100) for A232; for welding the order is A514 first (good, 55/100) then A232 (poor, 20/100).
