Nom. thick. e
Usage These general structural steel grades are characterised by a minimum yield strength of 185 – 360 N/mm2. Suitability for coldforming such as bending, folding, bordering and flanging etc. can be ordered separately. The of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. The welding technique used must be suitable for the intended application and comply with the state-of-theart. With distinctly closer chemical composition values and mechanical properties, the steel grades of the S235 – S355 series are used as material for wheels of enger cars, lorries and other vehicles.

The samples for the tensile test are taken at right angles to rolling direction unless the product width is opposed to this. 1) The tensile test values given in the table apply to longitudinal samples; in case of strip and sheet of widths of ≥ 600 mm they apply to transverse samlpes.

3) Average values of 3 samples; one individual value may fall short of the required minimum value by not more than 30%. The sample width shall equal the product thickness if the latter is between 5 and 10 mm. The tests are performed by using samples similar to Charpy-V samples. The values specified in the table above are to be reduced proportionally to the sample width.
Condition of delivery, scope of testing and certificate The provisions of DIN 10025-2, chapters 6.3 and 8 shall apply for delivery and inspection. Other inspections may be agreed.

1) The maximum nitrogen content shall not apply if the total aluminium content of the steel is at least 0.020 % or if it contains enough other nitrogenfixing elements. 2) Maximum carbon equivalent value CE = C + Mn /6 + (Cr + Mo + V) /5 + (Cu + Ni) /15 3) The steel is suitable for hot dip galvanizing, CE is raised by 0.2 %.
Welding No indications on weldability of steel grades S185, E295, E335 and E360 are made because there are no requirements on their chemical composition. The steel grades of the JR, JO, J2 and K2 categories are in general suitable for all welding techniques.
