Iron & Steel

The Chinese clan is the first country in the world to smelt iron and steel. Our ancestors mastered some skills of iron smelting, steelmaking, casting and forging and heat treatment three thousand years ago, more than 1700 years earlier than European countries. important contributions to human progress. Steel has become the most basic and important material for modern industrial and agricultural production, transportation, national defense and even people's life. At present, although various new inorganic materials and organic synthetic materials have been greatly developed. But in terms of production cost and wide applicability, they are far from being able to replace steel. Therefore, the production capacity of steel is still one of the important symbols to measure the national strength of a country. The reason why iron and steel materials are so widely used is that iron ore deposits are concentrated, the storage capacity is large, mining and smelting are relatively economical, and semi-finished steel products have strong cold and hot deformation capabilities. The finished product has excellent mechanical properties (strength, plasticity and impact resistance) and processing properties (cutting, welding, cold deformation, etc.). However, compared with silicic acid materials, polymer synthetic materials and some non-ferrous metals, its biggest disadvantage is that it is easy to lose weight due to corrosion and even completely destroy it in the atmosphere or under various media conditions such as acid, alkali, and salt. .

H-beams and I-beams are beams made of structural steel extensively used in construction applications. They are commonly used in building homes, bridges, large trailers, etc., due to the high strength imparted by them and the ease of construction.

Generally, steel box girder is connected by the top plate, bottom plate, web plate, diaphragm, mediastinum plate and stiffener through all welding. The top plate is an orthotropic bridge panel composed of a cover plate and a longitudinal stiffener. The thickness of each plate of a typical steel box girder can be: the thickness of the cover plate is 14mm, the thickness of the longitudinal U-shaped rib is 8mm, the width of the upper mouth is 300mm, the width of the lower mouth is 170mm, the height is 280mm, and the spacing is 620mm. The bottom plate is 10mm thick, and the longitudinal U-shaped stiffener ribs; Oblique web thickness 14mm, middle web thickness 9mm; Diaphragm spacing 4.0m, thickness 12mm; Beam height 2 ~ 3.5m. Steel box beam is a common structural form used in engineering. In order to study the influence of diaphragms spacing on the distortion of simply supported steel box girder under concentrated load, the distortion effect and rigid torsion effect of simply supported steel box girder with different number of diaphragms were compared under concentrated load, and the curve of maximum distortion effect with the number of diaphragms was obtained. The concentrated load is applied to the top of the box girder web, and the load decomposition method is used to calculate the four working conditions: distortion, rigid torsion, symmetrical bending and eccentric load.

Building Material Decorative Stainless Steel Sheet Metal 431 403 3mm 1mm Grade 431 stainless steels are martensitic, heat-treatable grades with excellent corrosion resistance, torque strength, high toughness and tensile properties. All these properties make them ideal for bolt and shaft applications. These steels, however, cannot be cold-worked owing to their high yield strength, hence they are suitable for operations such as spinning, deep drawing, bending or cold heading.

Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Galvanized sheet advantage 01.Anticorrosive:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities. 02.Cheap:The cost of hot-dip galvanizing is lower than that of other coatings. 03.Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable. 04.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use. 05.Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places. 06.Save time and energy:Galvanizing process is faster than other coating methods.

304 stainless steel is a common material in stainless steel, the density of 7.93g /cm³; Also known in the industry as 18/8 stainless steel, meaning containing more than 18% chromium and more than 8% nickel; High temperature resistance 800℃, has the characteristics of good processing performance, high toughness, widely used in industrial and furniture decoration industry and food and medical industry. Most of the requirements are to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be selected, the main consideration is the required aesthetic standards, the corrosion of the location of the atmosphere and the cleaning system to be used. However, other applications increasingly seek only structural integrity or impermeability. For example, the roofs and side walls of industrial buildings. In these applications, the owner's cost of construction may be more important than aesthetics, even if the surface is not very clean. 304 stainless steel works quite well in dry indoor environments. However, in rural and urban areas, it is necessary to wash frequently if it wants to maintain its appearance outdoors. In heavily polluted industrial areas and coastal areas, the surface can be very dirty and even rust. But to achieve the aesthetic effect in the outdoor environment, it is necessary to use nickel-containing stainless steel. Therefore, 304 stainless steel is widely used in curtain wall, side wall, roof and other architectural purposes, but in the serious erosion of the industrial or Marine atmosphere, the best use of 316 stainless steel. Stainless steel door, people have fully realized the advantages of using stainless steel in structural applications. 304 and 316 stainless steel are included in several design guidelines. Because "duplex" stainless steel 2205 has combined good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this steel is also included in the European guidelines. In fact, stainless steel is manufactured in all standard metal shapes and sizes, and there are many special shapes. The most commonly used products are made of sheet and strip steel, as well as medium and thick plates for special products, for example, hot rolled structural sections and extruded structural sections. There are also round, oval, square, rectangular and hexagonal welded pipe or seamless steel pipe and other forms of products, including profiles, bars, wires and castings.
