Steel A225 vs A514

Steel · grade comparison

Steel A225 and A514 are both steel grades. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 345 MPa (50 ksi) for A225, about 120% more; tensile strength follows at 800 MPa (116 ksi) vs 540 MPa (78.3 ksi). In exchange, A225 is the more ductile: elongation 24% versus 19% for A514, and A514 is harder (250 HB vs 160 HB). A225 conducts electricity better (8 % IACS vs 7 % IACS). On the shop floor, A225 machines more easily (good vs fair), A225 welds better (very good vs good), and A225 sits in a lower cost tier (budget, $) than A514 (standard, $$).

A225Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

A514Choose it when strength drives the design.
