Nom. thick. e

Usage
Suitability for coldforming such as bending, folding, bordering and flanging etc.
can be ordered separately.
The user 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
passenger cars, lorries and other vehicles.

1) 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.

Welding
The steel grades of the JR, JO, J2 and
K2 categories are in general suitable for
all welding techniques.

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) Copper contents higher than 0.400% can cause
exfoliation corrosion.
