The low corrosion resistance was due to surface passive film with less protective to reveal high anodic dissolution rate.The mechanism of corrosion is as also discussed.The oxidised 304 stainless steel is active on immersion, resulting in a low corrosion potential and a high weight loss. 304 vs 316 Stainless Steel - The Pros and Cons Arthur HarrisJul 28, 2017 · Both steels are durable and provide excellent resistance to corrosion and rust. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world, due to its corrosion resistance. 304 stainless is also cheaper in cost compared to 316, another reason for its popularity and widespread use.
The corrosion of stainless steels in steam increases regularly between 200 anil 300" C. This is not so in water:there, corrosion as function of temperature shows a marked maximum around 250" C for AISI 410 steel. For AISI 304 steel the maximum, which was not actually observed, must lie at a lower temperature. Influence of high temperature on corrosion behavior of 304 Dec 01, 2016 · AISI 304 Stainless Steel is widely used in many applications because of its mechanical and corrosion properties. However, its tendency to corrode PRELIMINARY COMMUNICATION Corrosion potential of 304 stainless steel in deaerated aqueous sulfuric acid of pH 1 revealed that the steel achieved a stable corrosion potential of ca. 0.350 V (SCE) independent of whether the electrode had previously been cathodically activated or anodically passivated.
Stress Corrosion Cracking The Alloys 304, 304L, and 304H are the most susceptible of the austenitic stainless steel to stress corrosion cracking (SCC) in halides because of their relatively low nickel content. Conditions which cause SCC are:(1) presence of halide ions (generally chloride), (2) residual tensile stresses, and (3) temperatures in excess of about 120°F (49°C). SCC - Stress Corrosion Cracking of Stainless Steelcorrosion cracking (SCC) of type 300 series austenitic stainless steels (SS), such as types 304 (UNS S30400), 316 (S31600), and their low-carbon forms, types 304L (S30403) and 316L (S31603). This diagram (Figure 1) is analogous to a similar diagram for caustic embrittlement of carbon steel un- method there is very little corrosion that occurs on AISI SS 304 at the concentration of 5% and 10%, which is only 6.8 mm / y. The figure shows that AISI SS 304 begins to corrode in the concentration of 15% of the solution, with a value of 24.8 mm / y. This shows that AISI 304 stainless steel has fairly good resistance to NaCl corrosion media.
