EN45 round bars, as an alloy steel, typically show strong resistance to corrosion, yet they remain vulnerable to galvanic corrosion when they come into contact with dissimilar metals along with an electrolyte. To reduce this risk, it is essential to apply protective measures like coatings and corrosion inhibitors, as well as to ensure proper material compatibility. Taking these precautions helps preserve the integrity and durability of EN45 round bars across a range of applications.
