904L stainless steel tube in the range of 0 ~ 98% pure sulfuric acid, 904L of the use of the temperature can be as high as 40 degrees Celsius. In the strong oxidizing nitric acid, 904L compared with the high alloyed steel without molybdenum.
Corrosion resistance is low. In hydrochloric acid, the use of 904L is limited to a lower concentration of 1-2%. In this concentration range. 904L corrosion resistance is better than conventional stainless steel.
904L steel has a high resistance to corrosion resistance. In the chloride solution, its resistance to crevice corrosion is also very good.
