904l Stainless Steel Tube
904L Seamless Stainless Steel Tube Description
904L Stainless Steel Tube (00Cr20Ni25Mo4.5Cu) is an austenitic stainless steel with enhanced corrosion resistance. Due to the addition of 1.5% copper, it also has excellent resistance to reducing acids such as sulfuric and phosphoric acid. Additionally, it has low carbon content, which is beneficial for welding purposes. Since the carbon content of 904L is very low (maximum 0.020%), there is no carbide precipitation during normal heat treatment and welding. This eliminates the risk of intergranular corrosion that typically occurs after standard heat treatment and welding. Due to its high chromium-nickel-molybdenum content and the addition of copper, 904L stainless steel tube can be passivated even in reducing environments such as sulfuric acid and formic acid. The high nickel content gives it a low corrosion rate even in the active state. In pure sulfuric acid with a concentration range of 0-98%, 904L can be used up to 40°C. In pure phosphoric acid with a concentration range of 0-85%, its corrosion resistance is excellent.
