The advantages of stainless steel heating tube 2016-10-14 The advantages of stainless steel heating tube are: better heat resistance, dry burning resistance, mature technology, and lower cost. At present, there are many types of stainless steel heating pipes used by the manufacturers of instant electric water heaters, and the price gap of various pipes is large. The same is the stainless steel electric heating tube, the difference in quality and performance is also very large. The difference between the quality of the stainless steel electric heating tube is mainly the nickel content. Nickel is an excellent corrosion-resistant material. After the stainless steel is combined with chromium, the corrosion resistance and process performance of the stainless steel can be improved to some extent. However, for low-carbon nickel steel to obtain a pure austenitic structure, the nickel content must reach 24%, and only when the nickel content is 27% can the corrosion resistance of the steel in certain media be significantly changed. Therefore, 800, 840, 316L are relatively good corrosion-resistant and high-temperature resistant stainless steel electric heating tubes in terms of materials. The 800 stainless steel tube contains 30% nickel, and the 840 tube contains 20% nickel. Some 304 tube stainless steel contains only 8% nickel. Therefore, the use of high temperature and corrosion resistant stainless steel heating tubes with high nickel content is also very advantageous.
