Steel 1035 vs E355

Steel · grade comparison

Steel 1035 and E355 are both steel grades. E355 is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 320 MPa (46.4 ksi) for 1035, about 53% more; tensile strength follows at 650 MPa (94.3 ksi) vs 585 MPa (84.8 ksi). In exchange, 1035 is the more ductile: elongation 18% versus 10% for E355, and E355 is harder (190 HB vs 163 HB). 1035 runs hotter in service (425°C vs 350°C continuous) and 1035 conducts electricity better (10.8 % IACS vs 8.6 % IACS). On the shop floor, E355 welds better (very good vs good) and 1035 sits in a lower cost tier (budget, $) than E355 (standard, $$).

1035Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

E355Choose it when strength drives the design, or when it will be welded.
