3 Ways To Prevent Metals From Corroding - WikiHow
One well-known example of a metal that exhibits passivation is stainless steel. Stainless steel is an alloy of ordinary steel and chromium that is effectively corrosion-proof in most conditions without requiring any other protection. For most day-to-day uses, corrosion isn't usually a concern with stainless steel. ... Retrieve Doc
How To Prevent Steel And Aluminum Corrosion - Structura
News How to prevent steel and aluminum corrosion October 13, 2016. Metals corrode when their environments are unsuitable. Virtually all metals used in construction or production are inherently unstable, and have a tendency to revert to other more stable forms by oxidizing or rusting. ... Retrieve Doc
21 Types Of Pipe Corrosion & Failure
The corrosion of steel piping and its related components is a continuous and virtually unstoppable process. The end product, which is commonly referred to as rust, is simply the result of an electrochemical reaction through which the higher energy-processed metal is slowly reverted back to its naturally occurring form: metal ore. ...

Corrosion - Wikipedia
Stainless steel can pose special corrosion challenges, since its passivating behavior relies on the presence of a major alloying component (chromium, at least 11.5%). Because of the elevated temperatures of welding and heat treatment, chromium carbides can form in the grain boundaries of stainless alloys. This chemical reaction robs the ... Get Doc

Galvanic corrosion potential is a measure of how dissimilar metals will corrode when placed against each other in an assembly. Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the corroding effect on the one higher in the list. ...

Case-hardening - Wikipedia
Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface. For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening process involves infusing additional carbon or nitrogen ... Read Article
