Question:

Are stainless steel sheets resistant to intergranular corrosion?

Answer:

Yes, stainless steel sheets are generally resistant to intergranular corrosion. This is because stainless steel contains a high percentage of chromium, which forms a protective oxide layer on the surface of the metal. This oxide layer acts as a barrier, preventing the metal from coming into contact with corrosive elements in the environment. However, in certain conditions, such as exposure to high temperatures or welding processes, the chromium in stainless steel can be depleted, leading to the formation of chromium carbides at the grain boundaries. This can result in intergranular corrosion, also known as sensitization. To mitigate this, stainless steel sheets can be treated through a process called stabilization, which involves adding elements like titanium or niobium to the steel to bind with the carbon and prevent the formation of chromium carbides. Overall, stainless steel sheets are highly resistant to intergranular corrosion, but precautions should be taken in specific situations to maintain their corrosion-resistant properties.
Yes, stainless steel sheets are generally resistant to intergranular corrosion due to the presence of chromium in their alloy composition. Chromium forms a protective oxide layer on the surface of stainless steel, preventing corrosive substances from penetrating the material and causing intergranular corrosion.
