S355J2+N coil — questions buyers ask
Is S355J2+N the same as EN 10025-2 S355J2+N?
EN 10025-2 S355J2+N, W.Nr 1.0577, High-strength structural steel are names used for S355J2+N (W.Nr / EN numbers and older UNS variants are the closest designations; their limits can differ slightly, so specify the UNS number and ASTM grade on the order), and coil is ordered to EN 10025-2 whichever name is on the enquiry.
Can S355J2+N coil be slit to width?
Yes. Coils can be slit to narrow widths for stamping, tube making and spring work; state width tolerance and coil weight on the enquiry.
What inner diameter do S355J2+N coils have?
508 mm (20") and 610 mm (24") are the common IDs. Tell us your decoiler ID and maximum coil weight and we slit to suit.
Can I order S355J2+N cut-to-length sheets from coil?
Yes. Coil can be levelled and cut to length; state length tolerance and flatness.
