Stainless steel is synonymous with durability and strength, but is it really indestructible? The term “stainless” can lead us to the misconception that stainless steel products never corrode. But let’s look at whether, when and why stainless steel can corrode, and how we can minimize this process.
Stainless steel is known for its ability to resist corrosion due to its chromium content, which forms a protective layer of chromium oxide on the surface. This layer is extremely thin but effective, protecting the steel from environmental influences. However, under certain conditions, it can be damaged and subsequently corroded.
- Damage to the protective layer: Thermal and mechanical stress, such as welding and grinding, can damage the protective chromium oxide layer.
- Contact corrosion: Contact with ordinary carbon or low-alloy steel can cause corrosion of stainless steel.
- Insufficient maintenance: Irregular cleaning and maintenance can lead to dirt buildup and subsequent corrosion.
In one project by an architectural firm, stainless steel was used for the facade elements of a building. Due to insufficient protection during construction, the surface was contaminated with particles of ordinary steel, which led to the formation of rust. However, after thorough cleaning and application of a protective coating, the surface was restored and its long-term durability was ensured.
Stainless steel is indeed durable, but not indestructible. Following the correct procedures for its processing and maintenance can significantly extend its lifespan. It is important to remember that even stainless steel can rust if not treated properly.
