Colored stainless steel plates   are much beautiful than ordinary stainless steel plates. The elevator decorated with colored stainless steel plate is imaginatively and attractively which welcomed by many customer. Here we will talk about its advantages:   1. Light weight. Color stainless steel plate replaces marble for its light weight and able to customed design that easy to replace.    2. Colorful. Etched patterns on stainless plate increase the exquisite appearance of the elevator hall door.   3. Cost saving. Do not need spotlights. The acrylic light line make colored stainless steel plate soft, warmer, and will not cause light pollution.

There are three types of cleaning methods for  stainless steel angle bar : mechanical method, physical method and chemical method.  1.       The mechanical method is to use the pressure, impact, shearing, grinding and other forces generated by various manual and power tools or different types of mechanical equipment to act on the castings to achieve the purpose of cleaning.  　 2.       The physical method is to use arc, plasma, laser, ultrasonic and shock waves to clean the castings. 3.       The chemical method is to use hydrofluoric acid to dissolve silicon dioxide and salt solution electrolysis to remove the sticky sand of small and medium-sized castings; some metals are also oxidized and gas-cut by the characteristics of intense oxidation at high temperatures.     HCADTO Stainless Steel Co., Ltd.   the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless...

Stainless steel seamless pipe   is a long steel pipe with a hollow section and no joints on the periphery. Features of stainless steel seamless pipe: 1. It has high economical and practical with thicker wall thickness., Since the thinner wall thickness have complicated process which increased production costs. 2. The inner wall of the stainless steel seamless pipe is smooth, the inner and outer surface of the pipe is high in brightness, and the resistance is small. 3. The inspection and shaping of stainless steel seamless pipes must be processed offline. Therefore, it embodies its superiority under  high-pressure, high-strength, and mechanical structural materials.

  1. Drop potion on the surface of stainless steel, and see the change of potion color to determine whether the material is 304 or 201. This method is very convenient, but not scientific. 2. Checking the spark when grinding the stainless steel plate. The sparks of 304 material form long sparks, while the sparks of 201 material are scattered. 3. Use magnets to absorb the stainless steel. 201 material is magnetic, while 304 material is non-magnetic, but 304 material may be magnetic after production, so we need to take at least two methods to identify . I hope that these methods may helpful to everyone in the judgment of 304 and 201 stainless steel.  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 g...

1.   Stainless steel pipes  should not have strip or spiral concave groove marks. The installation of shoddy stainless steel bright tube will endanger the sealing characteristics;  2. The stainless steel pipe should not be dragged out of the pipe rack or the rough surface layer, so as to prevent the impression of the concave groove;  3. Align the two ends of the stainless steel pipe and the socket of the double ferrule joint. If it is skewed, the installation will be laborious and the energy will be uneven, leading to more serious risks; 4. The pipe cutter should be kept sharp, and the pipe cutter should not cut too deep every time it rotates. And to ensure that the end of the tube after laser cutting has no burrs and no elliptical deformation. This is conducive to the smooth basis of the sealing gasket during the whole installation process, and it is not easy to destroy the sealing part of the sealing gasket.   HCADTO Stainless Steel Co., Ltd.   the Stainl...

The key difference between hot rolled   stainless steel angle bar   and cold rolled stainless steel angle bar is: 1. Cold-rolled formed steel allows partial buckling in the cross section, which can then flexibly use the load-bearing capacity of the component after buckling, while hot-rolled angle bar does not allow partial buckling in the cross section. 2. The causes of internal stress are different, and the spread on the cross section is also quite different. The internal stress on the cross section of the cold drawn thick-walled angle bar is bent, while the internal stress on the cross section of the hot rolled angle bar is of the plastic film type. 3. The random torsion stiffness of hot-rolled angle bar is higher than that of cold-rolled angle bar, so the torsion resistance of hot-rolled angle bar is better than cold-rolled angle bar.

 1. Furnace tightness The valve of the bright annealing furnace is closed and isolated from the outside air, if hydrogen is used as the maintenance gas, then only need one exhaust port. 2. Water vapor in the furnace Checking the charge to know if it is dry and the 304 stainless steel pipe entering the furnace is excessively water-containing. 3. Maintain the air pressure In order to avoid the occurrence of micro-leakage, the maintenance gas in the furnace should maintain a certain positive pressure. If it is hydrogen maintenance gas, usually it need to exceed 20kBar. 4. Does the annealing temperature reach normal temperature? The heat treatment of 304 stainless steel pipe adopts solution heat treatment, which is commonly referred to as annealing, and the temperature scale is 1040~1120℃. 5. Annealing atmosphere The annealing atmosphere of 304 stainless steel pipe is mainly selected from pure hydrogen. Because the purity of the atmosphere can not get to 100%.

Stainless steel channel bar   is a stainless profile with a channel-shaped cross section. Ordinary used materials are: 201, 202, 301, 304, 321, 316, 316l. The model of stainless steel channel bar is expressed in centimeters of waist height, and the specification range of channel bar is 5-40#. Marking requirements shall accord to GB2101-80. 1. Hot-rolled stainless steel channel bar (GB707-88) is mainly used in industrial structures such as building structures and vehicle manufacturing, and is often used in conjunction with I-beams. 2. Hot-rolled stainless steel light channel bar (YB164-63) has a better economic effect than ordinary hot-rolled channel bar. Its specifications range from 5# to 40#. In 1966, the metallurgical standard stipulated that the specification range was 10-40#. Main application: construction and steel frame structure.

The are three way to inspect   stainless steel channel bar : finished product inspection, mark inspection, and mechanical performance inspection. 1. All stainless steel channel bar should take visual inspection, to ensure the outside quality. 2. Inspection items  a) The surface of the base material of stainless steel channel bar shall not have cracks, surface pores, surface slag inclusion, scarring, folding and other defects whose depth exceeds the standard deviation.  b) The amount of misalignment in the width direction of the stainless steel channel bar should meet the requirements of the corresponding specifications and product standards. c) The depth and length of the surface depression should meet the requirements of the corresponding specifications and product standards.
