Astm A283 Gr.c NH Steel Plate is also known as Weather Resistant Steel Sheet, Weather Resistant Steel Plate.Weather-resistant structural steel is atmospheric corrosion-resistant steel, which belongs to low-alloy high-strength structural steel. According to its main characteristics, it is divided into high-weather-resistant structural steel and weather-resistant steel for welded structures. High-weather-resistant structural steel is made by adding a small amount of copper and phosphorus to steel , chromium and nickel elements to form a protective layer on the surface of the metal collective to improve the atmospheric corrosion resistance of the steel, and a small amount of molybdenum, niobium, vanadium, titanium, zirconium and other elements can be added to refine the grains and improve the performance of the steel. The mechanical properties of steel, improve the strength and toughness of steel, reduce the brittle transition temperature, so that it has better resistance to brittle fracture. Weathering steel for welded structure, the elements added to the steel, except for phosphorus, are basically the same as high weathering structural steel, and its function is also the same, and the welding performance is improved.
Weather resistant plate, i.e. atmospheric corrosion-resistant steel, is a low-alloy steel series between ordinary steel and Stainless Steel. Weather resistant steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of toughness, plastic extension, forming, welding and cutting, wear resistance, high temperature resistance and fatigue resistance of high-quality steel; The weather resistance is 2 ~ 8 times that of ordinary carbon steel, and the coating is 1.5 ~ 10 times that of ordinary carbon steel. At the same time, it has the characteristics of rust prevention, corrosion resistance, prolonging service life, thinning and consumption reduction, labor saving and energy saving. What is weather resistant plate - the application of weather resistant plate is mainly used for railways, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. It is used to manufacture petrochemical equipment such as containers, railway vehicles, petroleum derricks, port buildings, oil production platforms and containers containing hydrogen sulfide corrosive media.
The use of high weathering structural steel is mainly used for bolted, riveted and welded structural parts for vehicles, containers, buildings, towers and other structures due to its better atmospheric corrosion resistance than weathering steel for welded structures. When used as welded structural parts, the thickness of the steel should be no more than 16mm. The welding performance of weathering steel for welded structure is better than that of high weathering structural steel, and it is mainly used for welded structural parts of bridges, buildings and other structures.

Product Show：
The steel plate is a flat steel that is cast with molten steel and pressed after cooling.
The steel sheet is flat, rectangular and can be directly rolled or cut from wide steel strips.
The steel plates is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot rolling plate and cold rolling plate according to rolling.
Production Process：
1. Hot Rolled Steel Plate
Hot rolling processing methods include hot rolling, forging, extrusion and other methods.
2. Cold Rolled Steel Plate
Cold rolling processing methods include cold rolling, cold drawing and cold drawing, cold bending, cold extrusion and other methods.
The cold rolling method is to continue processing the hot rolled steel below the recrystallization temperature to make it cold rolled steel. Using cold rolling processing method can improve the mechanical properties of steel, and obtain products with high dimensional accuracy and certain smoothness.
Appliction:
Weathering steel is mainly used for railway, vehicle, bridge, iron tower, photovoltaic, high-speed engineering and other steel structures exposed to the atmosphere for a long
time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive
media in chemical and petroleum equipment.
