Corrosion in daily life - Steel frames on a balcony

Corrosion in daily life - Steel frames Looking at LinkedIn, corrosion may feel like an extremely intricate issue seen in large industries. However, looking around, we can see corrosion everywhere! Where was this photo taken? The photo above is of a steel frame attached to a balcony.  The part shown here is the bottom part of the frame. The coatings for such steel parts usually serve the purpose of moderate corrosion protection and more of aesthetics. If you observe, the thickness of the coatings also does not seem to be a lot. Why did the coating degrade? When it rains, the rainwater collects on the bottom of the frames.  This degrades the coating. At the places where it is not perfect anyway, the underlying steel is free to corrode. Most importantly, corrosion is more severe at the edges. It is severe enough to chip off the material entirely. That point is a prime site for crack formation and breaking of the frame. Have you seen such corrosion in your balcony frame? Let me

Need of 'CORROSION PLANNING'

Need for 'CORROSION PLANNING'  The importance of material selection cannot be stressed enough. With the equipment comes the material of the equipment, and every material is prone to corrosion in some way. For most fields such as defence, oil and gas, automotive, and marine, the qualification tests for the material selection begin and stop with the mechanical properties and composition. There is not even a mention of the possible corrosion phenomena for that particular material. This results in 'surprises' when there is a serious failure. Only after that are the corrosion investigations carried out and modifications done. However, by that time, it may be too late for some. Hence, it is necessary that the concerned personnel in the industries do not cut costs where corrosion is known to be an issue. What is Corrosion Planning? It is critical to begin a "CORROSION PLANNING" to ensure that the corrosion risks of every material that is qualified, and every componen
