About this calculator

Overview

Rust decay calculation estimates corrosion rate and material loss over time. Based on environment, material type, and protective coatings. Essential for maintenance planning.

Pro Tips

Galvanized steel: 50-100 year lifespan.
Painted steel: 10-20 years typical.
Stainless steel: minimal corrosion.
Salt air accelerates corrosion 5-10×.

Fun Facts

"Rust costs $2.5 trillion yearly globally."
"Iron oxide expands 6× original volume."
"Cathodic protection prevents corrosion."
"Galvanization: zinc coating protects steel."

Formula: Corrosion Rate = (Weight Loss) / (Area × Time × Density)
