S355J2H vs A1085
EN 10219-1 · Steel
Cold-formed welded hollow sections (SHS, RHS, CHS): 355 MPa yield, 470–630 MPa tensile, 27 J at −20 °C.
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.
Approximate345 MPa (50 ksi) yield with a 70 ksi cap, 450 MPa tensile, tighter wall tolerance; designed for seismic and full-thickness design.
