Steel 14G2AF-A vs 14G2AF-N

Steel · 14G2AF temper comparison

14G2AF-A and 14G2AF-N are two conditions of the same steel grade, 14G2AF: A (solution annealed) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 14G2AF-N is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 330 MPa (47.9 ksi) for 14G2AF-A, about 27% more; tensile strength follows at 570 MPa (82.7 ksi) vs 500 MPa (72.5 ksi). In exchange, 14G2AF-A is the more ductile: elongation 28% versus 24% for 14G2AF-N, and 14G2AF-N is harder (165 HB vs 145 HB).

14G2AF-AChoose it when the part is bent, formed or impact-loaded.

14G2AF-NChoose it when strength drives the design.
