Stainless steel pipes are ubiquitous in our daily lives. Many people are curious about why there are so many stainless steel pipe products in our lives. Therefore, the following article from Xinrenzhi will start with the three main characteristics of stainless steel pipes to help you better understand them.

　　1, corrosion resistance

　　Most stainless steel products require good corrosion resistance. Stainless steel tubes are similar to Class I and Class II cutlery, kitchen appliances, water heaters, water dispensers, etc. Some foreign traders also tested the product for corrosion resistance: using a NACL aqueous solution to warm to boiling, after a while the solution was drained, washed and dried to determine the weight loss to determine the degree of corrosion.

　　2, welding processability

　　The requirements for soldering performance vary by product. A tableware usually does not require soldering properties and even includes some pot companies. However, most products require raw materials with good welding properties, such as second-class tableware, vacuum flasks, steel pipes, water heaters, water dispensers, etc.

　　3, polishing

　　At present, stainless steel products are generally polished in the production process, and only a few products such as water heaters, water dispenser linings, etc. do not need to be polished. Therefore, this requires good polishing performance of the raw material. The main factors affecting the polishing performance are as follows:

　　1 raw material surface defects. Such as scratches, pitting, soaking, etc.

　　2 stainless steel pipe raw material problems. The hardness is too low, it is not easy to polish during polishing (BQ is not good), the hardness is too low, and the surface of the skin is prone to orange peel when deep drawing, which affects the BQ performance. High hardness BQ is relatively good.

3 After deep drawing, small black spots and RI high imitation DGING will appear on the surface of the deformed area, which will affect the BQ property.
