Steel 14G2AF vs Q460

Steel · grade comparison

Steel 14G2AF and Q460 are both steel grades. Q460 is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 430 MPa (62.4 ksi) for 14G2AF, about 16% more; tensile strength follows at 620 MPa (89.9 ksi) vs 580 MPa (84.1 ksi). Q460 is harder — 185 HB against 170 HB for 14G2AF — which matters for wear surfaces and threads. 14G2AF runs hotter in service (400°C vs 350°C continuous). On the shop floor, 14G2AF forms better (65 vs 55 out of 100).
