EN10155 S355J0W weather resistant steel

Category: Weather Resistant Steel

Updatetime: 21-Aug-2023

EN10155 S355J0W steel is a weather resistant steel which could more accurately be termed as an "Atmospheric Corrosion Resistant Steel" and often referred to as Corten-B steel. EN10155 S355J0W steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions and so on.

EN10155 S355J0W steel Chemical Composition by [%]

C	Si	Mn	P	S	Cr	N	Cu	CEV
max 0.16	Max 0.5	0.5 - 1.5	max 0.035	Max 0.035	0.4 -0.8	max 0.009	0.25-0.55	Max 0.52

Note:

The steels may show a Ni content of max 0.65 %;
For long S355J0W steel, the P and S content can be 0.005% higher;
The S355J0W steel may contain max. 0.30 % Mo and max. 0.15 % Zr
It is permissible to exceed the specified values provided that for each increase of 0.001 % N, the P max. content will be reduced by 0.005 %; the N content of the ladle analysis, however, shall not be more than 0.012 %
The max. value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0.020 % or if sufficient other N binding elements are present.
