What is the difference between Q355NH and Q355GNH to GB/T 4171 standard?

In recent years, in line with the development trend of iron and steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

S355J0 steel is a low alloy structural steel. We can supply S355J0 structural steel plates up to 400mm, with a minimum yield strength 355MPa when plate thickness less than 16mm, min. yield strength 345MPa when plate thickness range 16mm to 40mm. Without any special rolling or heat treatment for S355J0 steel plate and sheet, the abbreviated designation of this delivery condition shall be AR (As rolled).

The excellent properties of wear resistant steel plate meet the strict requirements of high strength, high wear resistance, stability, straightness and surface quality. The combination of high hardness, high strength and excellent impact toughness makes wear resistant steel plate become an ideal material for a wide range of applications. The production thickness of wear resistant steel plate is generally between 8-100mm.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the alloy wear-resistant steel plate is significantly improved.

Q355GNH to GB/T 4171 standard,DIN 17102 TStE285 steel plate/sheet,DIN 17102 TStE285 steel plate/sheet, under DIN standard, we can regard TStE285 steel plate/sheet as fine-grain structural steels, normalised rolled steels.DIN 17102 TStE285 is mainly used as ine-grain structural steels, normalised rolled steels. TStE285 steel plate/sheet is a hot rolled structural steels, which technical delivery conditions for normalized or normalized rolled in weldable fine grain structural steel grade.It is also regarded asEN10025:S275NL.UNE36081:AE285KTQ355GNH to GB/T 4171 standard

Q355GNH to GB/T 4171 standard,We are engaged in corten steel, weathering steel, atmosphere corrosion resistant steel materials.
