Steel 35# vs GX10CrMoV9-1

Steel · grade comparison

Steel 35# and GX10CrMoV9-1 are both steel grades. GX10CrMoV9-1 is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 330 MPa (47.9 ksi) for 35#, about 48% more; tensile strength follows at 660 MPa (95.7 ksi) vs 560 MPa (81.2 ksi). GX10CrMoV9-1 is harder — 215 HB against 160 HB for 35# — which matters for wear surfaces and threads. GX10CrMoV9-1 is stiffer (218 GPa vs 207 GPa) and GX10CrMoV9-1 runs hotter in service (600°C vs 400°C continuous). On the shop floor, 35# machines more easily (good vs fair), 35# welds better (good vs fair), and 35# forms better (fair vs poor).
