FAQs on S355JO+N Steel Plates
The "+N" indicates the plates have undergone normalization - a heat treatment process (heated to 890-950°C then air-cooled) that refines grain structure, improving mechanical properties and making the steel more uniform throughout the plate thickness.
Normalized S355J0+N offers: 15% better through-thickness properties, more consistent impact values across the plate, and reduced residual stresses - critical for welded structures and heavy load applications.
For thicknesses ≤25mm, preheat is typically unnecessary. For thicker sections (25-50mm), we recommend 50-100°C preheat. Our technical team provides free welding procedure specifications for your specific application.
Normalization provides better: 1) Through-thickness properties, 2) Consistency for heavy fabrications, 3) Stability for post-weld heat treatment, and 4) Long-term performance in dynamic load applications.
The key difference lies in impact testing temperature: S355J2+N is tested at -20°C while S355JO+N is tested at 0°C.
Common equivalent grades include ASTM A572 Grade 50, IS 2062 E350, and EN 10025 S355 grades depending on application requirements and mechanical properties.
S355JO+N plates are commonly available from 6mm to 300mm thickness depending on plate dimensions, mill availability, and project requirements.
