In-depth articles on metallurgy, materials science, and metal processing — written for engineers and learners alike.
Step-by-step tutorial on calculating corrosion rates. Covers weight loss coupon calculation (mpy/mm·year), Faraday’s law from corrosion current density, Stern-Geary B constant, and unit conversions.
Free corrosion rate calculator using the gravimetric weight-loss method per ASTM G1/G31. Outputs mm/year, mpy, µm/year, and g/m²/day from coupon weight loss, exposure time, area and metal density.
