Material introduction of stainless steel 334

The alloy of S33400 is an austenitic stainless steel containing titanium and aluminum. It contains enough chromium to form and maintain a sufficient scale of chromium oxide to protect it under high temperature conditions. It is more resistant to high temperatures than conventional chrome-nickel stainless steel such as 304. The higher nickel content makes it have better oxidation resistance than the standard 18-8 stainless steel, and its oxidation resistance is not inferior to the higher grades with temperatures up to 1900 degrees Fahrenheit (1038 ° C). alloy. Therefore, the 840 (S33400) alloy is an ideal material for the manufacture of electric heating pipes, automotive emission control systems and other high temperature resistant products.
