Stainless steel pipes can be found everywhere in our daily use. I believe
many friends are asking why there are so many stainless steel pipe products in
our life, so the following Xin coral small series will help everyone from the
three characteristics of stainless steel pipes. Better to understand.
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.
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,
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
