  • Isocorrosion chart

Use

  • Estimate corrosion rates for an alloy
  • Select an alloy for a particular application with specific parameters

Definition

  • A plot of temperature versus electrolyte concentration, with lines depicting combination where similar corrosion rates are found

example


how to use it?
  • An application needs a temperature and concentration as depicted by point 1 in the image above.
  • We can plot it on the isocorrosion chart for that alloy and estimate the corrosion rate.
  • The design of the component and corrosion allowance can be decided accordingly.
  • A method to determine the suitability of the alloy for an application and electrolyte-temperature combination.

Video below for practical demo of the use of the chart!

Corrosion - the bane of all the industries

By
Corrosion is the journey of an element from its most active form to its most stable form.  The birth At the place of its birth, inside the earth, an element such as iron comes into contact with atmospheric oxygen, chlorides, sulphate, and moisture. and is quite happy to remain in peace with them in the form of Fe 2 O 3 , Fe 3 O 4 , FeCl 3 and such. The growth It is then extracted and made to go through a number of processes which separate it from the ions and bring it to its elemental form. It is then put into use to make steel, where it coexists with carbon, manganese, chromium, and other alloying elements. The interaction However, iron has three electrons that it desperately need to give away. That is exactly what it does the moment the steel is brought out from the factory and put outside in the shed. Iron is more than happy to reunite with its old buddies - oxygen and moisture. It gladly gives away its electrons to them and returns to its peaceful state of Fe 2 O 3...

Important terms in API certifications - CRV & IOW - II

By
CRV can be understood by using a simple example of milk kept for boiling in a pot on a stove. The motive, i.e. the reliability of this process has two main factors - 1) The milk should boil. 2) It should remain the vessel and not overflow. There are three critical variables here - Temperature  Why is this a critical variable?  Answer: The melting point of milk is 92 degrees C. That is the optimum level. If temperature is too low (30 degrees C), the milk may not boil at all. If the temperature is too high (200 degrees C), it may burn quickly. Vessel dimension = volume of milk is 1 ltr Why is this a critical variable?  Answer:  Vessel volume < 1 ltr, milk will not fit in it in the first at all. Vessel volume = 1 ltr, milk will fit, but will overflow on boiling Vessel volume >1 ltr, milk will fit and not overflow. Time Why is this variable critical? If the other two variable are at the optimum level, then -  Too less time (~ 1 min), insufficient for milk to r...
