According to the national standard of hot rolled H-section steel in China (GB / t- H-section steel is divided into narrow flange, wide flange and steel pile, whose codes are Hz, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel W, IX and iy are not as good as H-section steel under the premise of equal weight.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, the solution temperature is ~ ℃, and the solution time is min.Patara,Galvanized steel pipe: in order to improve the corrosion resistance of steel pipe, general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Qatana, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality. China is a big steel country.Classification introductionThe cost is reasonable,What is the stainless steel passivation of alloy pipe?What are the uses of I-beam?Stages needing attention in the production and manufacture of alloy tubes

Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsdevice management,I-beam, whether ordinary or light,PataraHow much is 65 welded pipe per meter, so its application range is very limited. I-beams are widely used in buildings and other metal structures. China is a big steel country.I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China,Patara219 how much is a ton of seamless pipe, such as various alloy steel plates, cast wear-resistant plates,PataraMONEL400 alloy pipe, cast stones, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Patara,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min. Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, 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.
