Nominal thickness =< 63(mm)
For long products the P and S content can be 0.005% higher
For railway application a maximum S content of 0.01% may be agreed at the time of enquiry and order
In sufficient other N-binding elements are present the minimum total Al content does not applay
Cu content above 0.4% may cause hot shortness during hot forming

S355N steel plate is Non-alloy steel for structural purposes. S355N steel’s Mechanical properties is Yield strength more than 355MPa, tensile strength 450-630Mpa.
Structural Steels S355N steel is used in many applications, combining good welding properties with guaranteed strengths. S355N steel is used above all for manufacturing highly stressed welded structures in the construction of heavy machinery, bridges and steel structures. There are many grades and the uses varied including civil and industrial engineering. High strength low alloys have replaced many structural steels where weight reduction is important (e.g. automotive) but with guaranteed strengths
