How To Solve Various Problems in 304 Stainless Steel Pipe Processing

304 stainless steel pipes are usually 6M stainless steel pipes when they are sold. After processing, it is made into a variety of stainless steel pipe products, which are widely used in daily life.

But in fact, 304 stainless steel pipes often have various problems in processing. The following briefly summarizes the problems that are prone to occur in the processing of 304 stainless steel pipes and the solutions.

1. After 304 stainless steel pipe undergoes low-temperature and high-temperature finishing, welded stainless steel pipes may have welding defects and mechanical damage. For specific conditions, the machine needs to be repaired when necessary, and the appearance of the stainless steel pipe In the case of rust or spots, certain pickling and passivation steps should be carried out. However, if only pickling passivation is performed on the weld, the surface will be uneven and the aesthetics will be affected.

2. Pickling passivation treatment is carried out after manual polishing and polishing. It is difficult to achieve a uniform treatment effect for a workpiece with a large area, and an ideal uniform surface cannot be obtained. And the cost of working hours and auxiliary materials are also higher. Therefore, after finishing those surface treatments, in order to brighten the overall brightness of the stainless steel tube, so that it can better meet the general normal use and decoration needs, polishing technology can be appropriately selected.

3. The second is to eliminate the rust on the surface of the stainless steel pipe and the hidden dangers of possible corrosion. Alternating hot and cold processing of the stainless steel tube can promote the stainless steel material to obtain better strength and corrosion resistance. However, such processed stainless steel pipe materials are prone to pores, cracks, slag inclusions, etc. during welding. Some corrosive environments are prone to cause corrosion of stainless steel pipes. In this case, it is necessary to adopt corresponding mechanical treatment and chemical action to improve the corrosiveness of stainless steel pipes, so as to extend the service time of stainless steel pipes.

4. When 304 stainless steel pipe is processed, due to its unique hardness, the tool wears faster and it is more difficult to remove chips; when processing stainless steel pipe, use tools with higher thermal conductivity; and stainless steel tools need to be equipped with good toughness And higher cutting edge strength and bonding force of the coating film. The use of sharp cutting edge edges and a wider chip breaker land, which can reduce the cutting pressure, but also can well control the chip removal during processing;

5. Due to the low thermal conductivity produced during the processing of stainless steel pipes, it is easy to cause plastic deformation of the cutting edge and accelerate the degree of tool wear; proper processing conditions must be selected to maintain the service life of the tool.
