To know Stainless Steel Angle Bar in ONE MINUTE

图片
Stainless steel angle bar  also called angle iron. It is a long steel belt with straight sides. Stainless steel angle bar can be composed of various load-bearing members according to the different needs of the structure, also be used as a connection between the members. It widely used in various building structures and engineering structures, such as machine room beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power pipes, busbar support installation, And warehouse shelves, etc. Stainless steel angle bar is mainly divided into two types: equilateral angle bar and unequal angle bar. Unequal angle steel can be divided into two types: unequal edge thickness and unequal edge thickness. Equilateral angle bar is equiangular on both sides, and its specifications are expressed in millimeters of side width*side width*side thickness. For example: 30 * 30 * 3, indicating that the eq...

The Difference between Stainless Steel Seamless Pipe and Carbon Steel Seamless Pipe

Stainless steel seamless pipe  and carbon steel seamless pipe are widely used in industry, 1. Stainless steel becoming harden during cold working, for example, it has anisotropy during bending, the transverse and longitudinal properties are different. The strength increased by cold working, but if the bending area is small comparing to the total area and it can be ignored, the increased strength can improve the safety factor. 2. The shape of the stress/strain curve is different. The elastic limit of stainless steel is about 50% of the yield stress. As far as the small value specified in the standard is concerned, the yield stress value is lower than that of medium carbon steel. 3. Stainless steel has no yield point. Usually 60.2 is used to indicate that the yield stress is regarded as the local value.

The Classifications of Stainless Steel Angle Bar

Stainless steel angle bar  is one of the types of stainless steel profile, which is divided into two types: stainless steel equilateral angle bar and stainless steel heterotypic edge angle bar. And heterotypic edge angle bar can be divided into two types: equilateral thickness and unequal thickness. The specifications of stainless steel angle bar are expressed by the dimensions of side length and side thickness. Since 2010, the specifications of domestic stainless steel angle bar used No. 2-20, with the number of centimeters of the side. The same stainless steel angle bar has 2-7 different side thicknesses. Imported stainless steel angles indicate the actual size and thickness of both sides and indicate the relevant standards. Generally, the side length of 12.5cm or more is large stainless steel angle steel, the range of 12.5cm-5cm is medium-sized stainless steel angle steel, and the side length of 5cm or less is small stainless steel angle steel. The order of import and export sta...

Application, Protection and Maintenance of Stainless Steel Plate

Application of  stainless steel plate : The film must be removed after install the stainless steel plate. Then, clean the stainless steel plate with a special stainless steel cleaner. The common method is to use talc (double flying powder) to wipe. It is best to wipe it again with clean water, and dry it.  Why should tear off the film?  1.To avoid the phenomenon of glue retention caused by too long time or severe aging of the film can not be torn off.  2. If there is problem on the board surface, it can be found in time. 3. Preventing the contamination of liquid or corrosive liquid into the film can not be found, so that the board surface is exposed to moisture and corrosive environment for a long time, causing serious corrosion to the board surface. Stainless steel plate protection: If other projects are not completed, protective measures must be taken to protect the surface of the stainless steel plate after the film removed. Splashing in cement ...

The Advantages of Produce Stainless Steel Pipe by the Spinning Method

Spinning stainless steel production is a high-quality, precise, economical and flexible forming method. It uses stainless steel plates or stainless steel pipes as blanks, fixes the blanks on the mandrel, makes it rotate with the mandrel, and the spinning roller rolls along the mandrel to roll the blank into a shell with the same shape as the mandrel. This feature has aroused the strong interest and attention of the pressure processing personnel and made the spinning method get continuous development. The spin forming method has the following advantages: 1) The products produced by the spinning method have a smooth surface and high precision. For example, the shell with a diameter of 150mm can have an accuracy of +-0.005mm; the tolerance of the spacecraft shell is +-0.4mm, and it is easy to meet the requirements by the spin forming method.  2) After spinning the metal material, the grains are redistributed in the metal flow direction, which greatly improves the fatigue strength...

Application of Stainless Steel in Construction

The early application of stainless steel in the field of construction engineering began in the 1930s. For example, the Savoy Hotel in London, built in 1929, used stainless steel for ceiling and wall decoration. It has maintained a beautiful appearance for 70 years under the sea and environmental pollution. With the economic growth and the improvement of people's living standards, the good comprehensive performance of stainless steel, as well as the advantages of durability, beautiful appearance, long service life, and high cost efficiency, have been know by people. Municipal and bridges, tunnels and other public facilities to residential houses; from decoration, roofs, reinforced concrete, urban water supply projects to residential sinks, baths, stainless steel applications are becoming more and more widely. (1)Application in decoration engineering. In addition to walls, columns, automatic retractable doors, roller shutter doors, ladder fence handrails, balcony handrails, rain...

1. Introduction of  stainless steel angle bar : stainless steel angle bar also called angle iron. It is a long steel belt with straight sides. Angle steel can be composed of various load-bearing members according to the different needs of the structure, and can also be used as a connection between the members. It is widely used in various building structures and engineering structures, such as machine room beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power pipes, busbar support installation, And warehouse shelves, etc. The chemical composition of stainless angle bar are rolled steel series for general structure, and the primary verification objectives are C, Mn, P, and S. According to the different grades, the content is different, the approximate scale is C<0.22%, Mn: 0.30-0.65%, P<0.060%, S<0.060%. ​ (1) Inspection methods: ①Tensile test method...

MORE U-BEAM STEELS, LESS WASTAGE

The  U-beam steel  is a kind of long-strip steel whose cross section is in a groove shape. It is categorized as the carbon structural steel, which is able to be used for construction and machine manufacturing. U-beam steel is mainly used in the construction process of building structures, curtain walls, mechanical equipments and some vehicles. The most significant reason that the U-beam steel can be used so widely is that it is able to help the construction site to effectively save raw materials. This is beneficed to its good mechanical properties and perfect designed cross section. On the one hand, good mechanical properties bring the equilibrium epitaxy level to the surface of U-beam steel's cross section when this kind of steel profile is being rolled. It also has less internal stress than other traditional steel profile. Compared with I-beam steels, U-beam steels have larger cross sections and lighter per unit weight. They are helpful for decreasing the use level of non-...
