Different amounts of nickel

- May 05, 2018 -

Different amounts of nickel, nickel is an excellent corrosion resistant material, stainless steel and chromium in combination with the stainless steel corrosion resistance and process performance to get some improvement. However, for the low-carbon nickel steel to obtain pure austenite structure, the nickel content must reach 24%, and only when the nickel content is 27%, the corrosion resistance of the steel in some media can be significantly changed. Therefore, 800, 840, and 316L are relatively good materials for corrosion-resistant and high-temperature resistant stainless steel electric heating tubes. The 800 stainless steel tubes contain 30% nickel, and the 840 tubes contain 20% nickel, but if they are poor Some 304 stainless steels contain only 8% nickel. Therefore, the use of high-temperature corrosion-resistant stainless steel heating tubes with high nickel content is also very advantageous.
