Steel A202 vs A514

Steel · grade comparison

Steel A202 and A514 are both steel grades. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 350 MPa (50.8 ksi) for A202, about 117% more; tensile strength follows at 800 MPa (116 ksi) vs 570 MPa (82.7 ksi). In exchange, A202 is the more ductile: elongation 24% versus 19% for A514, and A514 is harder (250 HB vs 163 HB). A202 runs hotter in service (450°C vs 400°C continuous). On the shop floor, A202 machines more easily (good vs fair), A202 welds better (65 vs 55 out of 100), and A202 sits in a lower cost tier (budget, $) than A514 (standard, $$).

A202Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

A514Choose it when strength drives the design.
