What is Corrosion resistance?
Corrosion resistance is the property of a metal, or in general a material, to resist to corrosion attack in a particular environment at defined operating conditions, pressure, temperature and fluid velocity.
Usually the resistance to corrosion is expressed in terms of Corrosion rate, mm/y or mils.
Tables with corrosion rate for different fluids and operating conditions are available to estimate the corrosion resistance of a material.
The resistance to corrosion of a metal can be increased by means of corrosion control methods like cathodic protection, coating and painting or corrosion inhibitor.
