Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and a slight blunt edge. Flat steel can be finished steel, and can also be used as blanks for welded pipes and thin slabs for stacked sheets. Main application: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and it can be used as a house frame structure and escalator in construction. advantage The flat steel is rolled with negative deviation, but is delivered according to the actual weight, and the utilization rate is 1 to 5 percentage points higher than that of the steel plate. Flat steel can be produced with fixed thickness, fixed width and fixed length according to user needs, which reduces cutting for users, saves processes, reduces labor and material consumption, and also reduces processing loss of raw materials, saving time, labor, and saving. material. Products have been professionally used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, hoisting machinery and other industrial materials. Profile steel is one of the four major varieties of steel (plate, tube, profile, wire). According to the section shape, the section steel is divided into simple section section steel and complex section section steel (section steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, curved steel, etc. Square steel - steel with square section, hot-rolled and cold-rolled; hot- rolled square steel has a side length of 5-250mm; cold-drawn square steel has a side length of 3-100mm. Round bar - steel with round section, divided into three types: hot-rolled, forged and cold-drawn. The diameter of hot-rolled round bar is 5-250mm, of which 5-9mm is commonly used as the raw material for drawing steel wire, called wire rod; Disk supply is also called hot rolled wire rod. The forged round steel is straight and thick, and is used as a shaft blank. The diameter of cold-drawn round steel is 3-100 mm, and the dimensional accuracy is high. Angle steel - divided into two kinds of equal angle steel and unequal angle steel. The specification of angle steel is expressed by the dimensions of side length and side thickness. The specifications of angle steel usually produced are 2-20, that is, the number of centimeters on the side. For example, No. 5 equilateral angle steel refers to an angle steel with a side length of 5cm (50mm). The same horn often has 2-7 different side thicknesses. Calculation method of flat steel weight: Flat steel: weight per meter = 0.00785 * thickness * side width Please request a quote.

1.What is cold rolled steel? Cold rolled steel is steel produced by cold rolling. Cold rolling is a steel sheet obtained by further thinning the No. 1 steel sheet to a target thickness under room temperature conditions. Compared with hot-rolled steel sheet, cold- rolled steel sheet has more accurate thickness, smooth and beautiful surface, and also has various superior mechanical properties, especially in terms of processability. Because cold-rolled raw coils are relatively brittle and hard, and are not suitable for processing, cold-rolled steel sheets are usually required to be annealed, pickled and surface smoothed before being delivered to customers. The maximum thickness of cold rolling is below 0.1--8.0MM, for example, the thickness of cold rolled steel plate in most factories is below 4.5MM; the minimum thickness and width are determined according to the equipment capacity and market demand of each factory. 2.How is cold rolled steel processed? Using hot-rolled steel coil as raw material, after pickling to remove oxide scale, cold continuous rolling is carried out, and the finished product is rolled hard coil. The cold work hardening caused by continuous cold deformation increases the strength, hardness and toughness and plastic index of rolled hard coil. , so the stamping performance will deteriorate and can only be used for parts with simple deformation. Hard-rolled coils can be used as raw material for hot-dip galvanizing plants, because hot-dip galvanizing lines are equipped with annealing lines. The weight of the rolled hard coil is generally 6~13.5 tons, and the hot-rolled pickled coil is continuously rolled at normal temperature. The inner diameter is 610mm. 3.What are the relevant standards for cold rolled steel? GB905: Cold rolled round steel, square steel, hexagonal steel GB708: Cold rolled steel sheet and strip (1)Grade DC01、 DC02、 DC03、DC04、SPCC、SPCD、SPCE (2)Supply Standard GB/T 708,EN 10130:1998,JISG3141:2005 (3)Product Size (mm) Nominal thickness:0.3～3.0 Nominal width:20～1600 (4)Use Parts suitable for deep drawing of general forming knives songshunmoldsteel41404340

In addition to iron and carbon, alloy steel is called alloy steel by adding other alloying elements. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the difference of added elements and appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained. In addition to iron, carbon and unavoidable small amounts of silicon, manganese, phosphorus and sulfur, steel also contains a certain amount of alloying elements. The alloying elements in steel include one or more of silicon, manganese, molybdenum, nickel, antimony, vanadium, titanium, niobium, boron, lead and rare earth. This steel is called alloy steel of the alloy steel system. According to their respective resource conditions, it is found in my country that the alloy steel system mainly composed of silicon, manganese, vanadium, titanium, niobium, boron, lead and rare earth accounts for more than 10% of the total steel output. 8 categories. They are: alloy structural steel, spring steel, bearing steel, alloy tool steel, high speed tool steel, stainless steel, heat resistant stainless steel and electrical silicon steel.songshunmoldsteel41404340

1.The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron and rare earth. Among them, vanadium, titanium, niobium, zirconium, etc. It is a strong carbide forming element in steel. Given enough carbon, they can form their own carbides under the right conditions. When carbon is lacking or under high temperature conditions, they enter into solid solution in atomic state; manganese, chromium, tungsten, and molybdenum are carbide-forming elements, part of which enters solid solution in atomic state, and the other part forms substitute alloy cementite; aluminum, copper, nickel , cobalt, silicon, etc. are elements that do not form carbides and usually exist in solid solution in an atomic state. 2.There are many types of alloy steel, usually divided into low alloy steel (content <5%), medium alloy steel (content 5% ~ 10%) and high alloy steel (content > 10%). According to quality, it is divided into high-quality alloy steel and special alloy steel; according to its characteristics and uses, it is divided into alloy structural steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special properties. Steel (such as soft magnetic steel, permanent magnetic steel and non-magnetic steel). 3.Alloy steel contains more other elements than carbon steel Alloy steel refers to steel containing silicon and manganese as alloying elements or deoxidizing elements, as well as other alloying elements, and some also contain certain non-metallic elements. According to the content of alloying elements in steel, it can be divided into low alloy steel, medium alloy steel and high alloy steel. The carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a large amount of alloying elements, and is sometimes called ordinary carbon steel or carbon steel. Carbon steel is also called carbon steel, an iron-carbon alloy with a carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus. According to the purpose, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%)songshunmoldsteel41404340
