E355 Mechanical Properties

condition	Heat Treatment or Condition	Tensile Strength σ_b Mpa	Specified Plastic Yield Strength Rp_0.2 Mpa	Elongation or Extension Rate δ %
Steel tube	+CR1①②	≥540		≥5
Steel tube	+A	≥450		≥22

• +CR1：Welded and cold sized. Normally not heat treated
• +CR2：Welded and cold sized. Not heat treated
• +A：Soft annealed
• +N：Normalized

① For some strip grades, the degree of cold forming and the sizing of the as welded tube, may result in the yield strength being nearly be as high as the tensile strength. For calculation purposes yield strength values of R eH ≥ 0,7 R m are recommended for the +CR1 condition.
② The condition +CR2 may be specified with the same mechanical properties.
