5 thoughts on “What is a type steel? Is the reinforced steel?”
Phyllis
Steel is a type of steel with a certain cross -section shape and size. It is one of the four major varieties of steel (board, tube, type, and silk). According to the shape of the section, the type of steel is divided into simple section steel and complex cross -sectional steel (heterogeneous steel). The former refers to Fang Steel, Round Steel, Flat Steel, Clason Steel, Hexagon Steel, etc.; The steel bars are not steel, and reinforcement belongs to silk. Rebar refers to steel for reinforced concrete and prestressed reinforced concrete steel. Its cross section is circular and sometimes a square shape with a rounded corner. Including light round reinforced, ribs reinforced, reversing steel bars. Reinforced concrete reinforcement refers to a straight or plate -shaped steel for reinforced concrete with reinforced concrete. Its shape is divided into two types: light round reinforcement and deformation reinforcement. The delivery status is straight and plate circles. Extension information: -type steel classification 1, large -scale steel: large -scale steel Chinese work steel, slot steel, corner steel, flat steel are hot -rolled, round steel, square steel, hexagonal steel removal In addition to hot rolling, there are forging, cold pull, etc. 2, industrial steel, slot steel, and corner steel are widely used in industrial buildings and metal structures, such as factory buildings, bridges, ships, agricultural machinery vehicle manufacturing, power transmission tower, transportation machinery, and often use it. Bian Steel is used as a bridge, room rack, fence, transmission ship, vehicle, etc. in the construction site. Round steel and square steel are used as various mechanical parts, agricultural machinery accessories, tools, etc. 3, medium -sized steel: medium -sized steel, grooves, horns, rounds, and flat steels are similar to large -scale steel. 4, small steel: small steel middle corner, round, square, flat steel processing and use are similar to large-scale steel.

Steel steel is one of the four major steel varieties (plates, tube, type, silk). Depending on the shape of the section, the type of steel is divided into simple section steel and complex cross -sectional steel (different -type steel). The former refers to Fang Steel, Round Steel, Flat Steel, Clason Steel, Hexagon Steel, etc.;
square steel-square section steel, divided into hot rolling and cold rolling; hot-rolled square steel edges 5-250mm long; cold turtle steel edge length 3-100mm.
round steel-round section steel, divided into three types: hot rolling, forging and cold pull, hot-rolled round steel diameter of 5-250mm, of which 5-9mm is commonly used for pulling steel wire The raw material is called a wire; because the supply is also called hot -rolled bars. Forging round steel is thicker and use it as a shaft. The diameter of the cold pull round steel is 3-100 mm, and the size is high.
flat steel-12-300mm wide, 4-60mm thick, cross-section is rectangular and slightly pure steel. Flat steel can be a finished steel, or a thin plate for welding pipes and a thin sheet for tubing.
Corned steel -divided corner steel and non -equal corner steel. The specifications of corner steel are represented by the sizes of edge length and thickness. The corner steel specifications are usually No. 2-20, that is, the number of centimeters of the edge length. For example, corner steel such as No. 5 refers to corner steel with a length of 5cm (50mm). The same number of corner steel often has 2-7 different edges.
The steel bars are not type steel
The classification of steel
, black metal, steel and non -ferrous metal
Before the classification, briefly introduce the basic concepts of black metals, steel and non -ferrous metals.
1, black metal refers to the alloy of iron and iron. Such as steel, raw iron, iron alloy, cast iron, etc. Both steel and raw iron are based on iron and carbon as the main addition of elements, collectively referred to as iron carbon alloy. See -raw iron refers to the smelting of iron ore into the blast furnace, which is mainly used for steelmaking and manufacturing castings. This cast iron is placed in a melting iron furnace, that is, the cast iron (liquid -like) is obtained, and the liquid cast iron is cast into castings. This cast iron is called cast iron. The iron alloy is a alloy consisting of iron and silicon, manganese, chromium, titanium and other elements. Iron alloys are one of the raw materials for steelmaking. The deciduous and alloy element additives are used for steel.
2. Put the steelmaking iron into the steelmaking furnace and melt it according to a certain process, that is, the steel is obtained. Steel products include steel ingots, linked blanks, and directly cast into various steel castings. The steel usually refers to the steel made of various steels. Steel belongs to black metal but steel is not exactly equal to black metals.
3, non -ferrous metals, also known as non -iron metals, refer to metal and alloys outside black metals, such as copper, tin, lead, zinc, aluminum, and brass, bronze, aluminum alloy and bearings. In addition, chromium, nickel, manganese, molybdenum, cobalt, tungsten, tungsten, titanium, etc. are also used in industries. These metals are mainly used as alloy additives to improve metal performance. Among them, tungsten, titanium, molybdenum, etc. are mostly used to produce tools for production tools. Hard alloy. The above non -ferrous metals are called industrial metals. In addition, there are valuable metals: platinum, gold, silver and other rare metals, including radioactive uranium and radium.
. The classification of steel The steel is an iron carbon alloy with a carbon content of 0.04%-2.3%. In order to ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%. In addition to iron and carbon, the main elements of steel are silicon, manganese, sulfur, phosphorus, etc. There are many types of steel classification methods. The main methods are the following seven types:
1. Classification of quality (1) ordinary steel (P ≤ 0.045%, S ≤ 0.050%) r (2) High -quality steel (all P, S ≤ 0.035%) (3) Advanced high -quality steel (P ≤ 0.035%, S ≤ 0.030%)

Type steel, one of the four major steel varieties (plates, tubes, types, silk). Ben according to the shape of the section, the type of steel is divided into simple section steel and complex section steel (heterogeneous steel). The former refers to Fang Steel, Round Steel, Flat Steel, Clason Steel, Hexagon Steel, etc.;
