Listed as equivalent to
- S355 (EN 10025-2:2019) — Matches S355's yield (365 MPa ≤ 16 mm, 355 MPa 16–40 mm) with a higher tensile range, 520–640 MPa.
Not yet verified for this grade
- Yield above 40 mm (Total Materia shows ≥ 325 MPa without a band)
- A readable source for the 365 / 355 MPa bands
Missing on purpose: a value appears here only once a public source states it.
Sources here are public pages that reproduce JIS G 3106. For design and acceptance, the standard edition named in your specification and the inspection certificate (EN 10204 3.1) of the delivered product take precedence.
