904L flange ball valve Product overview:

904L flange ball valve is a valve body, valve cover, valve stem and ball and other main parts using 904L, N08904, 015Cr21Ni26Mo5Cu2 or S31782 super austenitic stainless steel material cast or forged from the ball valve, the material due to high chromium nickel molybdenum content, and added copper element, Therefore, even in the reducing environment, such as sulfuric acid and formic acid can also be passivated, high nickel content in the active state also has a low corrosion rate, in the concentration range of 0~98% pure sulfuric acid, the valve temperature can be as high as 40 degrees Celsius, in the concentration range of 0~85% pure phosphoric acid, its corrosion resistance is very good.

904L flange ball valve product advantages:

904L flange ball valve is developed by our company to meet the corrosion resistance in dilute sulfuric acid, which has been verified to be very successful after many years of practical application. The material used in the main part of the valve is a kind of high alloyed austenitic stainless steel with very low carbon content. The resistance to crevice corrosion in chloride solution is also very good. It has high resistance to stress corrosion cracking in chloride solution, concentrated hydroxide solution and hydrogen sulfide rich environment. This product is especially suitable for cutting off or connecting the corrosive media such as acetic acid, ammonium phosphate, electrolyte, oxalic acid, perphosphate and zinc sulfate in chemical industry pipeline system
