Steel 35A250 vs M19

Steel · grade comparison

Steel 35A250 and M19 are both steel grades. 35A250 is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 340 MPa (49.3 ksi) for M19, about 9% more; tensile strength follows at 500 MPa (72.5 ksi) vs 460 MPa (66.7 ksi). In exchange, M19 is the more ductile: elongation 25% versus 16% for 35A250, and 35A250 is harder (180 HV vs 150 HV). M19 is stiffer (200 GPa vs 190 GPa). On the shop floor, M19 welds better (50 vs 40 out of 100) and 35A250 sits in a lower cost tier (budget, $) than M19 (standard, $$).

35A250Choose it when strength drives the design, or when cost is the deciding factor.

M19Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
