Chloride Stress Corrosion Cracking Of 300 Series Stainless SteelBy Dr. Hira Ahluwalia
不锈钢的腐蚀（Corrosion of stainless steel）The corrosion resistance of stainless steel is due to the formation of a very thin, adherent and translucent chromium oxide film on the surface of stainless steel. Once the film is destroyed, the chromium in the steel will react with oxygen in the ...

Sunny steel has Stainless steel pipes for oil cracking inventory to fulfill your project’s needs, buy Stainless steel pipes for oil cracking at best price & fast delivery. The material of the stainless steel round bar is from Jiuli and Baosteel China, we control the quality from the very st...
Stress corrosion cracking (SCC) is a common mode of failure encountered in boiler components especially in austenitic stainless steel tubes at high temperature and in chloride-rich water environment. Recently, a new type of austenitic stainless steels called Super304H stainless steel, containing 3% ...
Stress corrosion cracking(SCC) 49% Stress corrosion cracking is to bear the stress of the alloy in the corrosive environment because of strong expansion of the alternate failure pattern of a generic term.
Theferritic steelsare characterized by good corrosion properties, very good resistance to chloride-inducedstress corrosion cracking(SCC), and moderate toughness. The toughness offerritic stainless steelsis generally not particularly high. Lower carbon and nitrogen levels give a considerable improvement in bo...
This paper presents the effect of buffing on the stress corrosion cracking (SCC) resistance of machined surfaces of AISI 316L stainless steel (SS). Surface finishing operations are known to lower the SCC resistance of austenitic stainless steels and yet are unavoidable. AISI 316L SS samples were ...
Recently in a fertilizers & chemicals plant, 304L stainless steel tubes used for cooling and condensing ammonia containing synthesis gases showed cracking after only about 6 months of service. Detailed failure analysis investigation was conducted to arrive at the cause of the failure and to recommend...
the destruction of the oxide film on the surface of steel, reduce the resistance to general corrosion and resistance to local corrosion (including pitting corrosion, crevice corrosion), and even lead to stress corrosion cracking. Stainless steel surface cleaning, pickling and passivation, in addition...
