Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.San Juan Dios,The use of welded steel mesh in China is still in its infancy. At present, the use of welded steel mesh in China accounts for less than one of the total amount of steel reinforcement. In the early s, steel welded mesh was listed as a key implementation project by the science and Technology Commission and the Ministry of construction, and specifications and procedures were formulated.Introduction to product knowledge of alloy pipe:Expansion zone,The shape of I-beam is similar to that of H-beam. What is the difference between them?Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:

a. In the forming process, the thick steel plate has uniform deformation, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe. Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY / t- is a submerged arc welded steel pipe for general low-pressure fluid transportation such as water, gas air and steam, which is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming and double-sided active submerged arc welding or single-sided welding.Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.Where is good,Function of I-beam: where is I-beam mainly used?It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape! Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason,San Juan DiosSuperalloy tube gh3039,San Juan DiosHow much is the I-beam of 28, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.

I-beam has wide flange, thin web many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Excellent service,Nitriding: also known as nitriding, gas nitriding is widely used in the production of alloy steel pipe.Galvanized pipe, also known as galvanized pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick, the coating is uniform, the adhesion is strong and the service life is long. The electroplating cost is low,San Juan DiosC-276 alloy pipe, the surface is not smooth, and the corrosion resistance is worse than that of hot dip galvanized pipe.→ I-beam can be processed into T-beam and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.San Juan Dios, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:In order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.
