  Many people don’t know what is the difference between hot-rolled and cold-rolled. As a professional  stainless steel angle bar   manufacturer, the staff will come to reveal this doubt for everyone. The main difference between hot rolled stainless steel angle bar and cold rolled stainless steel angle bar are:  　 　 1. The cold-rolled steel allows local buckling of the section, so that the bearing capacity of the bar after buckling can be fully utilized; while the hot-rolled steel does not allow local buckling of the section.  　 　 2. Hot-rolled steel and cold-rolled steel have different causes of residual stress, so the distribution on the cross section is also very different. The residual stress distribution on the section of cold-formed thin-walled steel is curved, while the distribution of residual stress on the section of hot-rolled or welded steel is thin-film.  　 　 3. The free torsional stiffness of hot-rolled steel is higher than that of cold-rolled s...

  Stainless steel angle bar   is a important type in the stainless steel industry, and its use methods and ways are better. The main use of stainless steel angle bar is due to its properties and main functions. Because of its rich functions, its physical and chemical properties are particularly good. Today we mainly solve one of the physical properties of stainless steel angle steel-density. Density is a unique property of a substance and one of the main physical manifestations. Therefore, most of the properties of stainless steel angle bar with good density are good. HCADTO Stainless Steel Co., Ltd.   the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless steel pipes, stainless steel angle bar, flat bar, round bar, square bar, hexagonal bar and channel bar in various grades and sizes. Our years of production experience and manufacturing facilities will ensure the good quality and competitive duration of our products.

  How to inspect  stainless steel pipe ? This is a very critical question. In order to ensure the quality and safety of stainless steel pipes, the quality of the pipe must be ensured. Let's learn the method of surface quality inspection of stainless steel pipes.  　　 1. If there is debris on the surface of the stainless steel pipe, especially when dust adheres, heating will certainly affect the oxide scale.  　　 2. If there is lubricating oil attached to the surface of the workpiece during cold working, it should be fully degreased in trichloroethylene degreaser and caustic soda solution and then cleaned with warm water and then heat treated. 3. The difference of the atmosphere in the stainless steel tube furnace The atmosphere in the furnace is different in various parts, and the formation of oxide scale will also change, which is also the cause of unevenness after pickling. Therefore, the atmosphere in each part of the furnace is the same when heating. 　 　 4. Objects...

Corrosion resistance The  stainless steel plate  has the ability to resist general corrosion similar to the unstable nickel-chromium alloy 304. Long-term heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require materials to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.   High temperature oxidation resistance Stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as exposure environment and product form.   Physical properties The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal.   HCADTO Stainless Steel Co., Ltd.   the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless steel pipes, stainless steel angle bar, f...

In order for the   stainless steel pipe   to be used for a longer time, the surface of the stainless steel pipe must be cleaned and maintained, so how should its maintenance and cleaning work be carried out?   Everyone must carry out timely cleaning and maintenance of the stainless steel pipe surface. When cleaning the surface of the stainless steel pipe, be sure to pay attention not to cause surface scratches, wire brushes, grinding special tools, etc., to prevent the application of bleach ingredients and abrasive cleaning fluids, and clean the surface with clean water after cleaning.   Stainless steel pipe is a steel with relatively good corrosion resistance. Therefore, most of the stainless steel pipes of many chemical companies and ships on the water use stainless steel industrial pipes. Compared with other stainless steel pipes, it can save a lot of maintenance time.   HCADTO Stainless Steel Co., Ltd.   the Stainless Steel Division of ADTO GROUP, speci...

The selection of   stainless steel plates   should consider the operating conditions, such as manual operation or automatic operation, the performance and type of the hot press, and the quality requirements of the pressed material such as hardness and gloss. We must also consider economic calculations. Every time a new steel plate is polished, it is required to produce a low-quality decorative plate. In addition, when choosing the most reasonable thickness of the steel plate, its service time, quality and rigidity should be considered.   At the same time, the strength requirements of the plate when it is compressed; heat conduction performance; pressure distribution, and the size of the press plate should be considered. If the thickness of the steel plate is not enough, it is easy to bend, which will affect the production of decorative panels. If the thickness is too large, the steel plate is too heavy, which not only increases the cost of the steel plate, but also brings...

  Stainless steel plates   are widely used in our lives. We also pay attention to its excellent performance. Many people are interested in the carrying capacity of stainless steel plates. In fact, its carrying capacity is to prove its quality in another way. 1.       The stainless steel plate adopts a pot bottom type structure. The design of this structure increases its force area to make its force more even.  　　 2.       In terms of material, the wear-resistant layer of the stainless steel plate uses multi-color quartz sand as a wear-resistant material and adds stabilizers, which virtually improves the wear resistance of the product. 3.       The use of continuous reinforced fiber skeleton ensures the high load-bearing capacity of the product and avoids the separation and shedding of other composite products due to the use of reinforcing materials such as steel bars.  　　 4.    ...

  Stainless steel angle bar  often undergoes a series of changes due to external factors. Once its surface is affected to a certain extent, its performance will be affected. As a result, the surface of the stainless steel angle bar is damaged. So what should we do?  　　   1.       The surface of stainless steel angle bar is cold welded or melted under pressure, and then the metal particles fall off due to relative movement and rapidly oxidize.   2.       After some stainless steel bar are quenched to form a supersaturated solid solution, they will be kept at room temperature or a slightly higher appropriate temperature for a long time to improve the hardness, strength or magnetic properties of the alloy.   3.       Heat treatment in a negative pressure atmosphere or vacuum, called vacuum heat treatment, can not only prevent the workpiece from oxidative decarburization, but also improv...

  Stainless steel angle  bar is a long strip of steel whose two sides are perpendicular to each other. There are equilateral angle bar and unequal angle bar. The two side widths of equilateral stainless steel angle bar are equal. Angle bar can be composed of various stress-bearing components according to different needs of the structure, and can also be used as a connection between components. It is widely used in various building structures and engineering structures, such as building beams, bridges, power transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.   Unequal stainless steel angle bar are widely used in various metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering structures, such as building beams, bridges, power transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers , Container...
