 Stainless steel products are being used more and more widely in the construction industry. What are the advantages of stainless steel products that make it so popular? 1. The appearance is beautiful and generous. The anti-fingerprint surface of stainless steel has a reflective effect, which makes it very popular in many occasions. 2. Anti-corrosion. Many construction occasions have very high requirements for the corrosion resistance of materials, and stainless steel materials greatly meet the requirements of users. For example, 304 stainless steel and 316 stainless steel. 3. Simple maintenance. As long as it is not used in places where the pollution is particularly serious, the maintenance cost of stainless steel products is low and the cleaning is simple. 4. Cost reduction. In recent years, the large-scale production of stainless steel products has reduced the price of stainless steel. The development of technology has also made stainless steel products more and more diversified,...

 When painting the surface of the  stainless steel plate , the details do well to get a good quality stainless steel plate. So what are the precautions when painting stainless steel plates? Let's take a look. 1. Basic treatment. If you want the film to be firm in the future, we must clean the surface of the stainless steel plate. We can use a knife to remove the original residual paint or sand the surface with sandpaper. It is easy to use sandblasting to make the surface rough and increase the adhesion area of the primer. 2. Spray primer. The function of primer is to prevent oxidation of the metal surface, and connect the topcoat and metal firmly . 3. Top coat. On the one hand, the paint film is required to have good weather resistance in the open air, on the other hand, it is extremely difficult to use a baking paint with a strong paint film. Therefore, it is recommended to use polyurethane paint, which is a two-component paint with a curing agent, without baking. The curing ...

  Forging is one of the important methods of plastic processing of stainless steel. The main purpose of forging is: forming and modification. Here, we will introduce you the forging process of   stainless steel pipe . 1. Die forging: When using stainless steel pipe as raw materials, the steel ingots should be rolled into bars in advance or used as die forging blanks after forging to eliminate the segregation, looseness and other defects in the steel ingots. After being heated, the blank is put into the die for forging, and the pressure causes the metal to flow and fill the cavity; if the blank after die forging has flash, it has to go through the steps of flushing the remaining material to complete all the forging work. 2. Free forging: Free forging can be used for special-shaped pipe fittings or stainless steel pipes that are not suitable for die forging. Free forging should forge the rough shape of the pipe fittings; such as tee, should forge its parts. 3. Cutting processing...

  304L stainless steel plate carbon content is lower than 304 stainless steel plate. 304L is better than 304 in corrosion resistance on solder joints. It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; high hot workability such as stamping and bending, no heat treatment hardening phenomenon (no magnetic, temperature -196°C~800°C). Tolerance is allowed, and dimensional tolerance is an absolute value without a sign. Limit deviation = limit size-basic size, upper deviation = maximum limit size-basic size, lower deviation = minimum limit size-basic size. The dimensional tolerance refers to the allowable amount of variation in the size of the part during cutting. In the case of the same basic size, the smaller the dimensional tolerance, the higher the dimensional accuracy.

  Improper inspection for the materials of   stainless steel angle bar   will cause safety hazards. In order to ensure production safety, stainless steel angle bar materials must to do strictly quality inspection. The below methods can be used to inspect stainless steel angle bar: Take the sample of stainless steel angle bar is sampled after the initial inspection passed. First, soaked the sample with hydrochloric acid with a concentration of not less than 14% to remove the rust. When there is no trace of seam during the hydrochloric acid soaking process, and polish it if have any doubt on it, use 4% nitric acid alcohol solution (need to use anhydrous alcohol ratio) to wipe and corrode the grinding surface of the sample. When the grinding surface of the sample loses luster or becomes dark, observe whether there are welds on the grinding surface traces appear carefully. Prohibited to put them in use before the result is release. After the test, the sample must be stored fo...

  201   stainless steel seamless pipes   are used as decorative pipes and are widely used in lots field. So soft or hard? which is better for 201 stainless steel seamless pipe? Two factors that affect the hardness of stainless steel seamless pipes are: steel strip annealing treatment and its carbon content. 1. The annealing of the steel strip of the stainless steel seamless pipe. The quality of the annealing is affect the hardness of the stainless steel seamless pipe directly. Whether it is 201 or 304 stainless steel seamless pipes, there are standards. 2. The content of carbon. The function of carbon in stainless steel seamless pipes is to increase the hardness of the pipe. However, carbon is an impurity in stainless steel. The more and the harder, the more rish of rust. 3. In fact, few people know that 201 stainless steel seamless pipes will add copper, and the copper not only improves the brightness of the pipe, but also increases the toughness of the pipe, which will ...
