Steels Resistant to Atmospheric Corrosion
These steels (S355J2G2W, ENSACOR or similar) are structural steels with high
elasticity, low alloy levels and fine grain, the resistance to atmospheric corrosion is
better than for other steels with similar mechanical characteristics. If they are used
uncoated, atmospheric oxide forms a patina on the surface that protects the steel.
They are mainly used in the construction of chimneys, bridges, containers, mining and architectural parts.
CHARACTERISTICS:
- Chemical composition and mechanical characteristics as per EN 10025.
- Good weldability.
- If they are painted, they double the life of the paint, due formation of a patina.
- They should not be used in atmospheres with a high concentration of free chlorine.
