Since the carbon content of 904L is very low (maximum 0.020%), there will be no carbide precipitation in the case of general heat treatment and welding. This eliminates the risk of intergranular corrosion after general heat treatment and welding. Due to the high chromium nickel molybdenum content and the addition of copper, 904L can be passivated even in a reducing environment, such as sulfuric acid and formic acid. High nickel content makes it have low corrosion rate in active state. In the concentration range of 0 ~ 98%, the service temperature of 904L can be as high as 40 ℃. The corrosion resistance of pure phosphoric acid in the concentration range of 0 ~ 85% is very good. In the industrial phosphoric acid produced by wet process, impurities have a strong influence on the corrosion resistance. Among all kinds of phosphoric acid, 904L has better corrosion resistance than ordinary stainless steel. In strong oxidizing nitric acid, 904L has lower corrosion resistance than high alloying steel without molybdenum. In hydrochloric acid, the use of 904L is limited to a lower concentration of 1-2%. In this concentration range. The corrosion resistance of 904L is better than that of conventional stainless steel. 904L steel has high pitting corrosion resistance. In chloride solution, its anti crevice corrosion ability is also very good. The high nickel content of 904L reduces the corrosion rate at pits and gaps. When the temperature of ordinary austenitic stainless steel is higher than 60 ℃, it may be sensitive to stress corrosion in a chloride rich environment. This sensitivity can be reduced by increasing the nickel content of stainless steel. Due to the high nickel content, 904L has high resistance to stress corrosion cracking in chloride solution, concentrated hydroxide solution and hydrogen sulfide rich environment.
