St33 Mechanical Properties

thickness t mm	Tensile Strength σ_b Mpa	Yield Point σ_s Mpa	Elongation or Extension Rate δ %
t＜3	310~540	≥185	8~14
3≤t≤16	≥290	≥185	16~18
16＜t≤40	≥290	≥175	16~18
40＜t≤100	≥290

① Tensile test values apply to longitudinal specimens for steel with a width < 600 mm; for steel with a width ≥ 600 mm, transverse specimens shall be used.
② U=hot-rolled, non-heat-treated; N=normalized.
③ Impact energy absorption: The average of three tests is taken as the test result. The minimum average value is 23 or 27 J, and only one individual value is allowed to be up to 30% below the maximum (average) value.
