E355 Mechanical Properties

product	Heat Treatment or Condition	Tensile Strength σ_b Mpa	Yield Point σ_s Mpa	Elongation or Extension Rate δ %
Tube	+U①②	≥540	ReH: ≥400	long: ≥5③
Tube	+A	≥490		long: ≥22③
Tube	+N	≥490	ReH: ≥355	long: ≥22③

• 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.
