High Quailty GB Q235NH / Q355NH / Q355GNH (MOQ20) / Q355C Atmospheric Corrosion Resistant Steel Plate

Short Description:

Atmospheric corrosion resistant steel (weathering steel) refers to a low alloy steel with good atmospheric corrosion resistance, which is made by adding a certain amount of Cu, P, C or Ni, Mo, Nb, Ti and other alloy elements to the steel. In industry, weathering steel has excellent atmospheric corrosion resistance because it forms a dense and stable oxide protective film on the surface of its substrate, which hinders the entry of corrosive media. However, the rust layer formed by corrosion on the surface of ordinary carbon steel substrate has a loose structure and micro-cracks, which cannot really protect the substrate steel..

Product Of Advantages

The main features of Q235NH steel plate include:

Processing properties: Hot-rolled steel plates have low hardness, are easy to process, and have good ductility. This makes it easier to shape and bend during processing.

Mechanical properties: Due to the softening of steel at high temperatures, hot rolling can improve the internal structure of the steel, making it tighter and stronger, thereby enhancing the mechanical properties. At the same time, under the action of high temperature and pressure, defects within the steel such as bubbles, cracks and looseness can be welded.

Surface quality: The surface quality of Q355GNH steel plate is relatively poor because an oxide layer is easily formed on the surface during the hot-rolling process and the smoothness is low.

Strength and toughness: Hot-rolled steel plates have relatively low strength, but good toughness and ductility. It is usually used to produce medium-thick plates and is suitable for applications requiring better plasticity.

Thickness: Q355NH steel plate can be of greater thickness, in contrast, cold-rolled steel sheets are usually smaller.

Application fields: Hot-rolled steel plates are often used in the production of structural steel, weather-resistant steel, automobile structural steel, etc., and are suitable for the production of various mechanical parts and the manufacture of high-pressure gas pressure vessels.

Main Application

Due to the absence of heating in the production process, there are no defects such as pitting and oxide sheet that often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and organization of products can meet some special requirements, such as electromagnetic properties and deep drawing properties.
2. Specification: The minimum thickness is 0.2-4mm, the width is 600-2 000mm, the length of the steel plate is 1 200-6 000mm.

Process of production

Hot rolling is a mill process which involves rolling the steel at a high temperature

which is above the steel’s recrystallization temperature.

Packing and Transportation

Packaging method: The packaging method of cold-rolled steel plate should comply with national standards and industry norms to ensure the safety and stability of the product. Commonly used packaging methods include wooden box packaging, wooden pallet packaging, steel strap packaging, plastic film packaging, etc. In the packaging process, it is necessary to pay attention to the fixing and reinforcement of packaging materials to prevent the displacement or damage of products during transportation.
