A992
The standard US steel for wide-flange beams: 50 ksi (345 MPa) yield, 65 ksi (450 MPa) tensile, Fy/Fu ≤ 0.85.
Compared with S355 on its equivalents table.
All values
Strength
Yield strength ReH
Upper yield strength guaranteed by the product standard (minimum).
| Condition | Value | Evidence |
|---|---|---|
| ≥ 345MPa | Corroborated |
Tensile strength Rm
Ultimate tensile strength. Product standards give a range or a minimum.
| Condition | Value | Evidence |
|---|---|---|
| ≥ 450MPa | Corroborated |
Ductility
Elongation after fracture A
Minimum elongation; depends on gauge length and test direction.
| Condition | Value | Evidence |
|---|---|---|
| ≥ 18% | Corroborated | |
| ≥ 21% | Single source |
Yield-to-tensile ratio Fy/Fu
Capped in seismic grades (A992: 0.85) so members can yield before they break.
| Condition | Value | Evidence |
|---|---|---|
| ≤ 0.85 | Single source |

Missing on purpose: a value appears here only once a public source states it.
Sources here are public pages that reproduce ASTM A992/A992M. 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.
