The material of stainless steel 334 is introduced

840 (S33400) is a kind of containing titanium and aluminum alloy austenitic stainless steel, chromium containing enough to form and maintain a sufficient size of chromium oxide, make its are protected under the condition of high temperature, than conventional chromium nickel stainless steel such as 304 more resistant to high temperature;High nickel content, compared to the standard of 18-8 stainless has better oxidation resistance and the oxidation resistance as temperature up to 1900 degrees f (1038 ℃), the higher grades of alloy.Therefore, 840 (S33400) alloy is manufacturing, automotive emission control system and other electric heating tube of high temperature resistant products ideal material. Stainless steel grade 334 can be applied in these areas: because of its formability, weldability and corrosion resistance and oxidation resistance of 840 alloy is a kind of common materials, electric heating tube used in the manufacture of electric heating tube, heat exchangers, heater equipment, industrial furnace and other equipment, also commonly used in automobile exhaust system.
