Short answer: Graphitization is a form of selective leaching in carbon and low-alloy steel and cast iron — long service at high temperature causes carbon to precipitate as graphite, leaving a soft, weak, brittle remnant. Avoid it by using low-carbon or alloy steels and by controlling weld heat and service temperature.
At a Glance
Where It Happens
Graphitization is a selective-leaching failure like Metal Selective Leaching Guide; estimate loss with Metal Corrosion Rate Calculation Guide and monitor via Metal Corrosion Monitoring Guide. Study structure with Metal Metallography Guide.
Prevent & Inspect
Use low-carbon or alloy grades and control weld HAZ; inspect by Metal Ndt Guide and document per Mill Test Certificate Guide. Protect stock via How To Prevent Metal Rust.
