P355N Chemical Composition,P355N Mechanical properties steel plate

P355N steel grade is a normalized, weldable fine grain steels for pressure purposed. The dimensions and tolerance on dimensions should be according to EN 10028-1.

P355N Chemical Composition:
C : <=0.2 Si:<= 0.5 Mn:0.9-1.7 S :<=0.03 N:<= 0.02 AL:<= 0.02 Nb:<= 0.05
P :<=0.03 Cr:<=0.30 Ni:<=0.5  Mo::<= 0.08 Cu:<= 0.30 Vi:<= 0.1 Ti :<= 0.03
Nb+Ti+V: <= 0.12

P355N Mechanical properties:
Tensile Strength σb(MPa) :
490-630 (thickness under 70mm);
470-610(thickness between 70-100mm);
450-590(thickness between 100-150mm);
Yield Strength σ0.2 :
>=355(thickness under 35mm);
>=345(thickness between 35-50 mm);
>=335(thickness between 50-70mm);
>=315(thickness between 70-100mm);
>=295(thickness between 100-150mm)
Elongation δ5(%) : >= 21

P355N Application:
EN 10028-3 P355N steel is mainly used to manufacture boilers and vessels which often worked in harsh environment, especially, high pressure, this environment requirements on steel is relatively high.

BEBON is a professional steel manufacture in China and we are specialized in hot rolled steel plate. But we also produce other kinds of steel products. And we could supply the min order is one steel plate and we promise to provide the competitive price in order to enlarge our oversea market.
