Corrosion Control

Introduction

The process of mass producing steel was discovered in the mid 1800’s by Sir Henry Bessemer, an Englishman who established the first steelworks in Sheffield. His discovery helped lead to the industrial revolution and steel is now one of the most common materials in the world. However, with its discovery came the problem of corrosion and therefore corrosion control.

Corrosion In Steel – The Cause

Corrosion – the deterioration of a material – is the result of the chemical interaction of a metal with its environment. Corrosion damage can take many forms, the rate and type of attack dependent on the physical and chemical conditions of the environment.

Corrosion Control – Sherardizing

It has been estimated that a quarter of all corrosion problems could be prevented easily by using well established techniques such as Sherardizing.

Sherardizing may be used as stand alone system in a purely sacrificial role, or as a component of a sacrificial and barrier protective system by the application of an organic or non-ferrous topcoat. Base materials suitable for Sherardizing are unalloyed carbon steel, low alloy steels, sintered material, malleable grey and cast iron.
