Detail the advantages of stainless steel tubes
● Corrosion resistance
Most stainless steel products require good corrosion resistance. For example, stainless steel tube is used for one or two kinds of tableware, kitchenware, water heater, water dispenser, etc. Some foreign businessmen even do corrosion resistance test to products. Heat NACL aqueous solution to boiling, pour away the solution after a period of time, wash and dry it, and weigh the weight loss to determine the degree of corrosion. (Note: During polishing, the abrasive cloth or sandpaper contains Fe, which may cause rust spots on the surface during testing)
The requirements for welding performance are also different for different product uses. A class of tableware on welding performance generally do not require, even including some pot enterprises. But the vast majority of products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, drinking machines and so on.
● Polishing performance (BQ)
At present stainless steel products are being produced generally through polishing this one working procedure. Only a few products, such as water heater, water dispenser liner, do not need polishing. So this requires that the polishing performance of raw materials is very good. The main factors affecting the polishing performance are as follows:
1. Surface defect of raw material. Such as scratches, pitting, pickling and so on.
2. Stainless steel pipe material problems. The hardness is too low, it is not easy to shine when polishing (BQ is not good), and the hardness is too low, it is easy to appear orange peel phenomenon on the surface when deep drawing, thus affecting BQ. BQ with high hardness is relatively good.
3. After deep drawing, small black spots and RIDGING will appear on the surface of the area with great deformation, thus affecting the BQ property.
Based on the five advantages of stainless steel tube, more and more people choose to use stainless steel tube, although the price is more expensive than other material stainless steel tube, but the cost performance is quite good.
