Corrosion Type of Stainless Steel Pipe

Gap corrosion: in the narrow gap, such as the flange or the connection of the thread, the gap in the passivation layer may be damaged, in the design, should be avoided as far as possible using flanges and threaded connections, to avoid the combined gap. In the welding process, should avoid undercut and so on.

Intergranular corrosion: Intergranular corrosion occurs in the chromium-poor areas, resulting in decreased corrosion resistance, corrosion in the strong acidic environment. Chemical Cargo ship stainless steel carbon content of less than 0.03%, after prolonged heating carbon content increases, and steel surface if subject to oil, grease, paint and paint pollution, prone to intergranular corrosion.
Stress corrosion cracking: it is austenitic stainless steel in the chloride ion, mechanical stress and temperature rise under the action of cracking, in the 60 ° below and the cargo tanks rarely occur stress corrosion cracking. It occurs occasionally in a heating coil (heating a chloride-containing semi-solid oil or exposing it to a seawater ballast tank containing chloride ions).stainless steel sheet supplier
Electrochemical Corrosion: Dissimilar materials may be electrochemically corroded due to electrolyte contact. When carbon steel and stainless steel welding, the active metal carbon steel accelerated corrosion. Under the driving of the electrolysis voltage, the electrolytic current between the two components causes electrochemical corrosion.316 Grade 8K Stainless Steel Plate/Sheet
