Super Austenitic 904L Capillary Tube Description
Super Austenitic 904L Capillary Tube is a low-carbon, high-nickel, molybdenum austenitic stainless acid-resistant steel. It has good activation-passivation transition ability, good corrosion resistance, and good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid. It has good resistance to pitting corrosion in neutral chlorine-containing media, as well as good resistance to crevice corrosion and stress corrosion.
Capillary tubes are used in various applications where precise control of fluid flow is required. Capillary Tubes are available in exact cut-to lengths and are also extremely operational in a wide range of high temperatures. These Capillary Tubes can be made in personalized thicknesses and sizes as per the specific requirements of our clients.
