Super austenitic stainless steel (904 L stainless steel plate) is a kind of very low carbon content of the high alloying austenitic stainless steel, in a dilute sulphuric acid has very good corrosion resistance, designed for corrosion strict environment and design. Has the high chrome content and enough nickel content, copper to make it has strong ability of acid, especially for chloride clearance corrosion and stress corrosion split a highly resistant, do not appear to corrosion damage spot and cracks, pitting corrosion resistance ability optimal and other steel slightly, with good manufacturability and weldability, can be used for pressure vessel.

note
1 welding performance
With general of the stainless steel, 90 4 L can use all sorts of methods for welding welding. The most common way for welding manual arc welding or sui gas shielded welding, electrode or welding wire based on the composition of the base metal and purity higher, molybdenum content requirements than the mother material. Before welding generally does not need to warm up, but in the cold outdoor work, to avoid the water vapor aggregation, and joint parts or close area can be evenly heating. Pay attention to the local temperature, no more than 10 0 °C, lest cause carbon concentration, cause intergranular corrosion. Welding the small line up-to-date energy, continuous and fast welding speed. After welding general need not heat treatment, heat treatment if you need, to be heated to 110 °C ~ 1150 after cooling rapidly.
2 machining performance
90 4 L of machining features similar to the other austenitic stainless steel, processing in the process to have stick knife and processing hardening of the trend. Shall be used is the former Angle carbide cutting tools, and chlorinated oil sulfide as cutting cooling fluid and equipment and technology should be to reduce the processing sclerosis as the prerequisite. Cutting should avoid using slow process of the cutting speed and feed quantity.
Editor this period
The corrosion resistance of the:
In general heat treatment and welding, won't have carbide exhalation, eliminate the heat treatment and general after welding appeared in the risk of intergranular corrosion. Due to the high cr-ni molybdenum content, and add the copper elements, so 904 L even in reducing environment, such as sulfuric acid and formic acid also can be dulled. High nickel content in the active state also have low corrosion speed. At 0 to 98% of the concentration range of pure sulfuric acid, the use of 904 L temperature can be as high as 40 degrees Celsius. In 0 ~ 85% concentration range of pure phosphoric acid, the corrosion resistance is very good. In the wet process in the production of industrial phosphoric acid, impurities, have very strong performance against corrosion effects. In all phosphoric acid, 904 L stainless steel corrosion resistance is better than the ordinary. In strong oxidizing of nitric acid, 904 L and contains no mo of steel high alloying compared, corrosion resistance is low. In the hydrochloric acid, the use of 904 L limited to low concentration 1-2%. In this concentration range. 904 L stainless steel corrosion performance is good in the conventional. 904 L steel has the very high resistance to corrosion function point. Chloride solution in the crevice corrosion resistance ability is also very good. 904 L high nickel content, lower the gaps in the pit and the corrosion speed. Ordinary austenitic stainless steel in temperature more than 60 degrees centigrade, in a rich chloride environment of stress corrosion may be sensitive, by increasing the nickel content in stainless steel, can reduce the sensitization sex. Because of the high nickel content, 904 L in chloride solution, concentration of hydrogen chloride solution and rich hydrogen sulfide environment, has the very high resistance to stress corrosion cracking ability.
