Causes of corrosion in railway wagon
Water seepage through the flooring to the top of trough floor
Design allow the rain water flow through the panel and drainout at the bottom
Leakage of water through lavatory flooring.
Blockage of drain water by accumulated dust on top oftrough floor
Dissimilar metals joint
Design allow space7

Areas Subject To Corrosion In Wagon
Side wall bottom : area below lavatory and between body sidepillars
Body pillars : bottom portion of pillar near doorways andlavatory area
Body side door : bottom of door due to accumulation of dust
Roof : ventilator and area around it
Joint between frame (carbon steel) and roof (stainlees steel)

Prevention
1. Use of HSLA : CORTEN STEEL
3. Surface preparation and painting (organic coating)
4. Use simillar metals which are welded or joined togather
2. Use of corrosion resistant material like stainless steel

Corrosion Resistance is corten steel standard of Indian
railways specifically formed for wagon body , due to it
high resistance to corrosion
Corten steel (often referred to as CorTen) is a weather
resistant steel which could more accurately be termed as an
"Atmospheric Corrosion Resistant Steel
CORTEN STEEL

Conclusion
Corrosion my occur in the corrosive atmospheric
Corrosion can be mitigated by :
avoiding usage of dissimilar metals,
use simple design
good coating and the preparation or cleaning, and
choose a material with good resistant to the corrosion
