How To Distinguish The Quality Of Stainless Steel Heating Tubes

The quality of stainless steel depends mainly on the difference in nickel content. Nickel is a high-quality corrosion-resistant element. The perfect combination with chromium in stainless steel further strengthens the corrosion resistance and acid and alkali resistance, but the low-carbon nickel steel needs to obtain pure austenite. The body composition, the nickel content should reach 24%, and only the copper content of 27% can make the corrosion resistance of steel in some media change significantly. Therefore, for the heating pipe, the corrosion resistance and high temperature resistance can be selected as 800, 840, 316L, etc., 800 stainless steel tube contains 30% nickel, 840 tube nickel content reaches 20%, 316L stainless steel tube nickel content 10%, but if it is used in a poor 304 tube stainless steel containing only 8% nickel.

Advantages of stainless steel heating tube: good heat resistance, dry burning resistance, low cost. At present, there are many types of stainless steel heating tubes, and the price difference between various materials is large. It is also stainless steel material, and its quality performance is also very different.

Therefore, the purchase of stainless steel pipes for heating pipes needs to be tested for the specific element content, so as to prevent shoddy filling and low-quality products at high prices.
