Steel 16NC6 vs A514

Steel · grade comparison

Steel 16NC6 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 16NC6, about 117% more; tensile strength follows at 800 MPa (116 ksi) vs 560 MPa (81.2 ksi). In exchange, 16NC6 is the more ductile: elongation 22% versus 19% for A514, and A514 is harder (250 HB vs 170 HB). A514 runs hotter in service (400°C vs 300°C continuous) and 16NC6 conducts electricity better (8 % IACS vs 7 % IACS). On the shop floor, 16NC6 machines more easily (good vs fair) and 16NC6 sits in a lower cost tier (budget, $) than A514 (standard, $$).

16NC6Choose 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, or when the part sees heat.
