P355NL1 Steel Plates comes in different standards such as GB, JIS, ASTM, DIN and so on. The process for making these plates is hot rolling and the heat treatments are as rolled, controlled rolling and or normalized. Suryadeep Industry is a leading supplier of these plates and we manufacture different dimensions and scales of EN 10028-3 P355NL1 Pressure Vessel Steel Plates products. The plates range from 5mm to 150mm in thickness, 1000mm to 4500mm in width and 3000mm to 18000mm in length. Cut to length sizes are also available from us. The EN10028 P355NL1 plates material is made up of carbon, silicon, manganese, phosphorus, sulfur, aluminum, nitrogen, chromium, copper, molybdenum, niobium, nickel, titanium and vanadium in the composition.
This composition provides the P355NL1 Mill Plates with very high yield and tensile strength properties. The tensile strength for plates less than 16mm in thickness is up to 630MPa and the minimum yield strength is 355MPa. The plates of higher thicknesses have less strength but not lower than 295MPa minimum yield strength and not less than 450MPa minimum tensile strength. The P355NL1 grade is used in the applications such as pressure pipe components, apparatus engineering, compressors, pressurized gas tanks, pressure vessels and in fine grain structural steels that can be welded. The P355NL1 Plates applications also include some elevated temperature applications such as the steam boilers, boiler components, heaters and heat exchangers. Please contact us for detailed information on the P355NL1 Material and the pricings.
