Steel for construction and engineering according to the classification of use without phase transformation or partial phase transformation of square tube: A. ordinary carbon structural steel; b. Low alloy structural steel; c. Steel reinforcement.Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.Abbotsford,Strictly feed Si Ca wire quantity to ensure effective & Omega in steel; When (CA) is about .%, the inclusions can be fully denatured without generating more high melting point inclusions.Square pipe for conveying flammable and non flammable fluids, Standard No.: gbt (gbt - ). The representative material is l-l pipeline steel. It is mainly used to transport flammable and non flammable fluids. Low pressure or high pressure square pipes have high requirements. The purpose of large-diameter qb square pipe is qb square pipe, C-shaped steel and H-shaped steel. It is mainly used in the construction of simple plant, steel structure and other infrastructure. Qb square pipe is generally used as the frame and purlin of the plant. C-shaped steel Steel is an important support for the plant, and H-section steel is used as load-bearing. Especially in recent years, a large number of small and medium-sized enterprises have started to build spacious and bright plants. If traditional buildings are built, the time is slow, if the investment in the plant is too high and the investment is large. For some small and medium-sized enterprises, the capital will be produced after operation Serious impact. The plant built with qb square tube, C-section steel and H-section steel has the characteristics of time saving, money saving and fast use. Therefore, the sales of qb square tube, C-section steel and H-section steel have increased significantly in recent years and become the first choice for plant construction. Qb square tube, C-section steel and H-section steel are mainly used in the construction of simple plant steel structure and other infrastructure The qb square tube is used as the frame and purlin of the plant. The C-shaped steel is used as the important support of the plant, and the H-shaped steel is used as the load-bearing. Especially in recent years,AbbotsfordCold galvanized square pipe factory, a large number of small and medium-sized enterprises around the country have started to build spacious and bright plants. If the traditional buildings are built, the time is slow, and the investment is large. For some small and medium-sized enterprises Said that if the investment in the plant is too high, it will have a serious impact on the capital after operation. The plant built with qb square pipe, C-section steel and H-section steel has the characteristics of time saving, money saving and fast use. Therefore, the sales of qb square pipe, C-section steel and H-section steel have increased significantly in recent years, becoming the first choice for plant construction. Large diameter qb square pipe plant is introduced Shao measures for effective wrinkle of seamless square pipe: check the wrinkle state even when the wrinkle around the part is determined to be less than the clamping force, it should be increased to increase the inner diameter of the inner plate and the tensile stress of the wrinkle drawbead. Adopt the principle of loosening after tightening to loosen after tightening and ask Question.Tiadiaye,Pig iron refers to the product made by smelting iron ore in blast furnace. It is mainly used for steelmaking and square casting. Put the cast pig iron in the melting furnace to obtain cast iron (liquid), and cast the liquid cast iron into a cast square pipe. This kind of cast iron is called cast iron.Steel for construction and engineering according to the classification of use without phase transformation or partial phase transformation of square tube: A. ordinary carbon structural steel; b. Low alloy structural steel; c. Steel reinforcement.The second is the pickling of the square pipe. Both chemical and electrolytic methods are used when pickling the square pipe. These two methods can remove the oxide skin of the square pipe.

Square tube plays an important role in the rapid economic development. The functions of square tube are different and its characteristics are also different. Square tube has strict standards. There are many welding processes and advantages of square tube. Let me show you the welding process and advantages of lower tube.First, or use phosphate or chromate solution, brush, spray or dip coating. After the fixed reaction time, rinse the acid solution with plenty of fresh water on the surface.B. spring steel C. bearing steel tool steel: A. carbon tool steel; b. Alloy tool steel; c. High speed tool steel.Customer first,Generally speaking, square pipe welding has a process: ignition, pressurization and thermal insulation.Square pipe is the name of square pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment.Square tube nonferrous metals, also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin, lead,Abbotsford180 galvanized square pipe, zinc, aluminum, brass, bronze, aluminum alloy and bearing alloy. In addition, chromium, nickel, manganese, molybdenum, cobalt square tube vanadium, tungsten, etc. are also used in industry. These metals are mainly used as alloy additives to improve the performance of metals. Tungsten, square tube titanium, molybdenum, etc. are mostly used to produce cemented carbide for tools. The above non-ferrous metals are called industrial metals. In addition, there are precious metals: platinum, gold, silver and rare metals, including radioactive square tubes.

Special performance steel: A. stainless and acid resistant steel; b. Heat resistant steel: including oxidation resistant steel, heat strength steel and air valve steel; c. Electric heating alloy steel; d. Wear resistant steel; e. Low temperature steel; f. Electrical steel.market,The disadvantage of empty bending is that when the upper side and side are synchronously empty bending, the forming force is easy to exceed the critical point due to the pressure generated by the upper roll and the lower roll at the same time, resulting in edge instability and concave, and will also affect the stable operation and forming quality of the unit. This is also the different characteristics of qb square tube and round tube empty bending. The concept of square tube: square tube is the pressure processing of ingot, billet or square tube Make materials of all shapes, sizes and properties we need.After the square pipes are stacked and stored, the pipe end protector shall be removed to avoid moisture gathering on the surface of the pipe end protector and the square pipe, which is difficult to volatilize.With the improvement of production quality, the quality of square tubes is getting better and better. The quality of square tubes will affect our lives. Because the functions of square tubes are different, their characteristics and uses are different. I will introduce the characteristics and uses of square tubes in detail.Abbotsford,A. square tube structural steel: (a) high quality carbon structural steel; (b) Alloy structural steel; (c) Spring steel; (d) Easy cutting steel; (e) Bearing steel; (f) High quality structural steel for specific purposes.: it refers to the processing of square tube, which places metal in a closed Jane and applies pressure at the end to extrude the metal from the specified die hole to obtain finished products with the same shape and size. It is mostly used to produce non-ferrous metal materials. Square tube ferrous metal, steel and non-ferrous metal. Before introducing the classification of steel, briefly introduce the basic concepts of ferrous metal, square tube steel and non-ferrous metal.High quality steel (P & le; .%, S & le; .%)
