S355J2H (EN 10210, hot finished) vs A1085
EN 10210 · Steel
Hot finished hollow sections: 355 MPa yield up to 16 mm, 470–630 MPa tensile — and fu = 490 MPa in design, not the 510 MPa of cold-formed EN 10219 sections.
ASTM A1085/A1085M · Steel
US HSS with a yield cap: 50–70 ksi (345–483 MPa), 65 ksi (450 MPa) tensile, same for round and shaped.
