A36 vs S235
ASTM A36/A36M · Steel
The classic US carbon structural steel: 36 ksi (250 MPa) yield, 58–80 ksi (400–550 MPa) tensile.
EN 10025-2:2019 · Steel
Mild structural steel: 235 MPa minimum yield up to 16 mm, 360–510 MPa tensile.
ApproximateYield 250 MPa (36 ksi), between S235 and S275; tensile 400–550 MPa. No impact test unless ordered.
