E235 Mechanical Properties

product	Heat Treatment or Condition	Tensile Strength σ_b Mpa	Yield Point σ_s Mpa	Elongation or Extension Rate δ %
Tube	+U①②	≥390	ReH: ≥300	long: ≥7③
Tube	+A	≥315		long: ≥25③
Tube	+N	≥340	ReH: ≥235	long: ≥25③

• long = longitudinal ; tr = transverse.

① For outside diameters ≥ 1 68,3 the values for the normalized condition apply.
② Includes delivery condition +NW.
③ Values are for longitudinal testing and are reduced by 2% for transverse testing.
