Corrosion Resistant Alloy (Buy Online from Stock)

Corrosion Resistant Alloys (also known as CRAs) provide essential long-term corrosion resistance to various components which are exposed to environments associated with oil and gas production. 

A corrosion-resistant alloy (CRA) is an alloy consisting of metals such as:

Chrome
Cobalt
Nickel
Iron
Titanium
Molybdenum

There are many different Corrosion Resistant Alloys to choose from and are usually categorised according to their resistance levels when exposed to particular environments.

Some key environmental parameters which play a part in influencing the corrosion properties of Corrosion Resistant Alloys include:

Temperature
Partial pressure CO2
Whether sulphur is present or absent
Environment pH
Chloride ion concentration
Partial pressure H2S


The above parameters can influence:

The passive film’s stability (initiation of general corrosion or pitting)
Repassivation ease of initiated pits
Dissolution rates or metal from pits
The Stress Corrosion Cracking (SCC) risk, initiating and propagating
