Full comparison

“Equivalent” tables online usually match grades by name. This one compares the values each standard actually guarantees, so a 30 MPa gap in yield is visible before it is in your calculation.

Grade	Standard	Min. yield at 10 mm	Tensile at 10 mm	Match	What differs
S235	EN 10025-2:2019	≥ 235MPa4	360–510MPa4	—	Reference grade.
Q235B	GB/T 700	≥ 235MPa3	370–500MPa3	Close match	Same yield steps (235/225/215 MPa) and impact qualities; tensile 370–500 MPa vs 360–510.
SS400	JIS G 3101	≥ 245MPa2	400–510MPa2	Approximate	Higher yield (245 MPa ≤ 16 mm) and tensile (400–510 MPa), but no impact test and almost no chemistry limits: not for welded primary structures.
A36	ASTM A36/A36M	≥ 250MPa3	400–550MPa3	Approximate	Yield 250 MPa (36 ksi), between S235 and S275; tensile 400–550 MPa. No impact test unless ordered.
E250	IS 2062:2011	≥ 250MPa1	≥ 410MPa1	Approximate	Yield 250 MPa, tensile ≥ 410 MPa; impact qualities BR (room temperature) and B0 (0 °C).
