Steel 35NCD16 vs A514

Steel · grade comparison

Steel 35NCD16 and A514 are both steel grades. 35NCD16 is the stronger of the two: yield strength 1,620 MPa (235 ksi) against 760 MPa (110 ksi) for A514, about 113% more; tensile strength follows at 1,900 MPa (276 ksi) vs 800 MPa (116 ksi). In exchange, A514 is the more ductile: elongation 19% versus 11% for 35NCD16, and 35NCD16 is harder (530 HB vs 250 HB). A514 runs hotter in service (400°C vs 200°C continuous) and A514 conducts heat better (42 W/m·K vs 35 W/m·K). On the shop floor, A514 machines more easily (fair vs poor), A514 welds better (good vs poor), and A514 sits in a lower cost tier (standard, $$) than 35NCD16 (high, $$$$).

35NCD16Choose it when strength drives the design.

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