Overview
Because the carbon content of 904L is very low (maximum 0.020%), there will be no carbide precipitation under general heat treatment and welding conditions. This eliminates the risk of intergranular corrosion after general heat treatment and welding. Due to the high content of chromium, nickel and molybdenum and the addition of copper, 904L can be passivated even in reducing environment, such as sulfuric acid and formic acid. The high nickel content makes it have a lower corrosion rate in the active state. The corrosion resistance of 904L is better than that of conventional stainless steel.
904L steel has high resistance to pitting corrosion. In chloride solution, its crack corrosion resistance is also very good. The high nickel content of 904L reduces the corrosion rate at pits and crevices. 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.
