Angle is built with carbon structural steel, is a simple section steel steel, mainly used for metalcomponents and the frame of the plant. In use requires a good weldability, plastic deformation and certain mechanical strength. The production of raw materials for low carbon steel billetsteel billets, finished angle for the hot rolling, normalizing or hot-rolled state of delivery.

Type specification

Mainly divided into equilateral angle steel and equilateral angle steel two categories, includingunequal angle can be divided into equilateral equilateral thick and unequal thickness two.

Angle specifications expressed with side length and edge thickness size. At present domesticsteel specifications for 2 - 20 cm in length, number number, the same horn steel often have 2- 7 different edge thickness. The actual size and edge inlet angle marked on both sides of thethickness and indicate the relevant standards. The general length of more than 12.5cm for large angle, 12.5cm - 5cm for the medium angle, length below 5cm for small angle.

Inlet and outlet angle steel orders generally required the use specifications in the main, thesteel is carbon steel grades corresponding. Is the angle in addition to standard number, nospecific composition and performance series. Angle iron delivery length is divided into fixed length, double length two, domestic angle of fixed length of choice scope has 3 9m, 4 12M, 419m, 6 19m four scope according to the specifications of different. Japanese angle length selection range is 6 - 15m.

Section unequal angle height according to the long edge of the width to calculate the scalene angle steel. Refer to section for angular and both sides unequal in length of steel. Is an angleof. Its length from 25mm * 16mm to 200mm * l25mm. From the hot rolling mill and rolling.General specifications for: scalene angle steel angle 50*32-- angle 200*125 thickness of 4-18mm

Unequal angle steel is widely used in all kinds of metal structures, bridges, machinery manufacturing and shipbuilding, building structure and engineering structures, such as beams, bridges, power transmission tower, lifting the transport machinery, ships, industrial furnace, reaction tower, container frame and warehouse etc..

Q:What's the chemical reaction between stainless steel and galvanized angle iron?
The essential condition for stainless steel to be corrosion resistant is that the mass fraction of chromium must be greater than 10~12%. When the temperature increases, the diffusion velocity of carbon in the grain of stainless steel is higher than that of chromium. Because the solubility of carbon in austenite at room temperature is very small, about 0.02% ~ 0.03%, and the carbon content in austenite stainless steel are generally more than this value, the excess carbon will continue to austenite grain boundary diffusion, and chromium compounds, compounds of chromium carbide in the crystals, such as 23C6 (CrFe) etc.. The data show that chromium diffusion along the grain boundary activation capacity of 162 ~ 252KJ/mol, and Cr intracrystal diffusion activation energy is about 540KJ/mol, namely: chromium by intracrystal diffusion faster than chromium diffusion along the grain boundary velocity is small, the chromium was too late to grain boundary diffusion, so the main chromium chromium carbide formed in intergranular required not from the austenite grain interiors, but from the vicinity of the grain boundaries, the chromium content makes near the grain boundary is reduced, when the mass fraction of the grain boundary chromium low to less than 12%, the formation of the so-called "chromium depleted zone", in corrosion, will lose the chromium depleted zone corrosion resistance, and intergranular corrosion.
Q:Double angle steel rod in the corners of the roof steel why need to set the plate?
A rod is a member of a much larger dimension than a horizontal (vertical) direction. The beams, columns and other components in the building are generally abstracted as rods. The shape and size of the rod can be described by two major geometric elements, the cross section and the axis of the rod. A cross section is a vertical section perpendicular to the length of the bar, and the axis is the center of each cross section. The cross section and the axis of the rod are perpendicular to each other. A rod with the same axis and straight line and cross section is called a straight rod with equal section. Building mechanics and mechanics of materials are mainly concerned with equal section straight bars. The bar whose cross section changes along the axis is called a cross section bar.
Q:Is there a screw that can be made like angle iron, but not a right angle, just a single piece of material? Just put
As for the cutting of wood cutting machine can cut metal with no blade, you can find a corner grinder to cut angle grinder specifications you can use with 100 or 125 with the same diameter, diameter, cutting slice thickness 3mm, slice should be perpendicular to the cutting piece.
Q:Unequal angle steel
Expansion:The dimension of equilateral angle iron is expressed by the width of the edge * the width of the side and the thickness of the millimeter. Such as: 30*30*3, which means that the width of the edge is 30mm, and the thickness of 3mm is equal to the angle of steel. Also available models (Tex) said that the model is the number of centimeters wide. The front angle types symbols "/" models, behind the upper right corner with the symbol "#", such as: / 30#. The specifications for equal angles are 2#-20#.
Q:What does "angle length" and "limb width" mean?
Also available models that model is the number of centimeters wide, such as angle 3#. The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:What is angle iron?
The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container rack and warehouse shelves, also used to protect column, wall parts easy to hit.
Q:What is the difference between galvanized steel bar and ordinary angle iron?
Galvanized angle iron is divided into hot galvanized steel angle and cold galvanized steel angle. Galvanized steel galvanized or hot-dip galvanized steel angle is also called. Cold galvanized coating mainly through the electrochemical principle to ensure full contact between zinc powder and steel, resulting in electrode potential difference for corrosion protection.
Q:What is angle flower? Is it the same as angle iron?
The angle iron is the foundation of the angle steel and is punched out through the holes,
Q:What is the corresponding length of the root weight in the angle standard?
General fixed length delivery without weighing, no fixed length delivery is generally applied to weighing sales. Profile fixed length is generally divided into 6 meters, 9 meters and 12 meters, special sizing must be large quantities, consultation with the steel supply.
Q:What is the angle iron back machine?
With the development of the power industry, the manufacturing level of the power tower is becoming more and more demanding, and the planer processing method can not meet the requirements of production. The company's own design and manufacture of "CB2512" shovel back machine, the use of high-speed milling principle, used for angle steel shovel back process, the tower is the production of angle steel shovel back the first choice of equipment
