Steel 30CrMnTi vs A514

Steel · grade comparison

Steel 30CrMnTi and A514 are both steel grades. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 480 MPa (69.6 ksi) for 30CrMnTi, about 58% more. A514 is harder — 250 HB against 207 HB for 30CrMnTi — which matters for wear surfaces and threads. 30CrMnTi conducts electricity better (7.8 % IACS vs 7 % IACS). On the shop floor, 30CrMnTi machines more easily (good vs fair), A514 welds better (good vs poor), and 30CrMnTi forms better (fair vs poor).

30CrMnTiChoose it when the part is machined in volume, or when cost is the deciding factor.

A514Choose it when strength drives the design, or when surface hardness matters.
