The 09CuPCrNiA weathering steel plate contains a variety of elements. Weathering steel is composed of copper, phosphorus and chromium, manganese, titanium and antimony. Generally, E4301 or 4303 welding rods, or old brands J423CuP, J422CrCu, J422CrCu, etc. should be used. Because of the low strength level, the copper and phosphorus content is lower, and its content is less than 0.25%, so the hot crack and cold brittle tend to be small. Therefore, the welding process is the same as that of low alloy high strength steel Q390 steel. 09CuPCrNiA matrial is a kind of high-strength weathering steel. The combination of Cu and P can resist the corrosion of the atmosphere. In addition, Cr and Ni are all materials used in stainless steel, such as weathering steel, which is resistant to atmospheric corrosion. Between the stainless steel and the stainless steel, a small amount of copper, chromium, nickel and other elements are added to the carbon steel.
Application of 09CuPCrNiA Weathering Steel Plate
The 09CuPCrNiA weathering steel sheet is divided into weathering steel for welded structure and high weather resistant structural steel. Weathering steel, which is resistant to atmospheric corrosion steel, is a series of low-alloy steels between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel and a small amount of corrosion-resistant elements such as copper and nickel. It has the toughness and plasticity of high-quality steel. Characteristics of elongation, forming, welding, abrasion, high temperature, fatigue resistance; weather resistance is 2 to 8 times that of ordinary carbon steel, and coating is 1.5 to 10 times that of ordinary carbon steel. At the same time, it has rust resistance and makes components Anti-corrosion and life extension, thinning and reducing consumption, saving labor and energy. Weathering steel is mainly used for railways, vehicles, bridges, towers and other steel structures that have been exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, Structural components such as containers containing hydrogen sulfide corrosion media in seaport buildings, oil production platforms and chemical petroleum equipment.
Thickness of 09CuPCrNiA Weathering Steel Plate
The 09CuPCrNiA steel plate is more than 4mm. The steel plate with thickness >20mm to 60mm is called thick plate, high pressure vessel steel plate and pattern steel plate. It is also called strip steel. The steel plate with thickness > 60mm needs special thick plate mill. Upper rolling, armor steel and composite steel, etc., so called extra-thick plate, in actual work, so the productivity is higher than single-frame mechanism. 6mm-3, boiler steel plate, small width, automotive steel plate, bridge steel plate, steel belt In fact, it is a very long thin plate. 09CuPCrNiA steel plate with a thickness of less than 20 mm is often referred to as a medium plate. 0 mm. The width of the thick steel plate is from 0. 09CuPCrNiA Thick plates are divided into shipbuilding steel plates according to their purpose. One branch of the steel plate is a steel strip, which is cut into a fixed length and is a steel strip, which is often supplied in rolls.
Prime 09CuPCrNiA Weathering Steel Plate
09CuPCrNiA weathering steel sheet is a high-quality supply material for engineering in large-scale steel plate landscapes. Often in the multi-stand continuous rolling mill production of steel plate is not long rust stage, the naked eye can not distinguish between genuine weathering steel plate and ordinary hot-rolled steel plate, 1, need to refer to the steel factory's warranty book, the warranty book requires suppliers to provide a steel factory red chapter The original, so as not to make the business inferior. Common materials for authentic weathering steel are 09cupcrnia, B480GNQR, etc. of Baosteel or Anshan Iron and Steel, and the materials of ordinary hot-rolled steel are q235b, SPHC, etc. The authentic weathering steel has a clear and dense rust core layer, and the rust spots are closely adhered to form a protective layer. The hand rubs almost no rust; the ordinary steel plate has a large amount of rust, and even the whole piece of rust peels off and rust wears. Genuine weathering steel is biased towards reddish brown, and ordinary steel is biased towards dark black.
Properties of 09CuPCrNiA Weathering Steel Plate
The 09CuPCrNiA weathering steel plate GNH is the intention of the "high weathering" Chinese pinyin initials. (The national standard naming principle, most of which is now in line with international standards), D is the grade, indicating that low temperature impact toughness is required, standard: GB/T 4171-2008 "weathering structural steel". High weathering steels are more resistant to atmospheric corrosion. Authentic weathering steel begins to grow small rust spots, the rust point of ordinary steel plate is loose, some rust treatment is poor, and even rust skin appears; genuine weathering steel rust water is less, rust point is thicker and thicker; rust water of ordinary steel plate More rust spots are larger and thinner; the rust column and tear marks of ordinary steel plates are more serious, and there are signs of blackening at the bottom of the workpiece.
