S355 vs E350
EN 10025-2:2019 · Steel
Europe's workhorse structural steel: 355 MPa minimum yield up to 16 mm, 470–630 MPa tensile from 3 to 100 mm.
ApproximateYield 350 MPa for the thinnest band, 5 MPa below S355; minimum tensile 490 MPa, above S355's 470.

Rows are matched by condition (thickness band, temperature, product form). A dash means the grade has no sourced value for that condition. Differences are E350 relative to S355; for ranges the lower bound is compared.
