Tensile strength class A
S235J0 steel Usage
Hot rolled products of structural steels EN 10025-2 S235J0 steel equal to Chinese 
standard steel grade GB_Q235C.These two steel grades are both done low 
Temperature impacting test at zero centi degree 

Suitability for coldforming such as bending, folding, bordering and flanging etc. S235j0 steel can be ordered separately. The user ofS235j0 steel 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, S235j0 steel is used as material for wheels of passenger cars, lorries and other vehicles.

S235j0 steel Chemical composition

Grade	C≤ 16mm max	C>16mm max	Si max	Mn max	P max.	S max.
S235J0	0.17	0.17	--	1.40	0.045	0.045

 

 

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.
3) Maximum carbon equivalent value
CE = C + Mn /6 + (Cr + Mo + V) /5 + (Cu + Ni) /15

1) The tensile test values given in the table apply to longitudinal samples (l); in case of strip and sheet steel of widths of ≥600 mm they apply to transverse samples (t).
2) It applies to nominal thickness e:
e < 3 mm: A80
e ≥ 3 mm: A5

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 0 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.
