Corrosion resistant alloys are also referred to as “CRA’s”, and they are a popular material in the world of welding and construction due to their high resistance to, you guess it, corrosion. There are various beneficial properties of corrosion resistant alloys, all of which have their own unique applications and functions in various industries all across the nation.
Continue reading to learn more about corrosion resistant alloys, including some common types, what they are best used for, and where you can recycle scrap metal materials in Indiana.
Corrosion Resistant Alloys (CRA’s)
Corrosion resistant alloys are a type of metal that is specially designed and manufactured to resist deterioration, discoloration, degeneration, and other kinds of corrosion. There are many kinds of CRA’s to choose from, all of which ranging in level of resistance. Elements and condition like temperature, CO2, Sulphur, environmental pH, and chloride ion concentration all affect resistance capabilities. These factors in turn affect the passive film’s stability (commencement of overall corrosion or pitting), re-passivation ease of initiated pits, dissolution rates or metal from pits, and the stress corrosion cracking (SCC) risk.
Common CRA’s on the Market:
There are various kinds of Corrosion resistant alloys available on the market today, however, there are 3 in particular that seem to take the lead on current trend. These include 316L (austenitic stainless steel), alloy 22, and Zeron® 100.
316L (Austenitic Stainless Steel) – The most common applications for 316L CRA include clad line pipe building, surface piping, and vessel cladding. One downfall is that it will pit of exposed to oxygen.
Alloy 22 – Alloy 22 is a CRA that is used for conditions that require resistance to oxidizing acid chlorides, wet chlorine, mixtures containing nitric acid or oxidizing acids with chlorine ions, formic and acetic acids, ferric and cupric chlorides, brine, salt water, and even reducing acids like sulfuric acid and hydrochloric acid.
ZERON® 100 – ZERON® 100 is highly resistant to both pitting and corrosion in the presence of salt water, stress corrosion cracking, and similar elemental conditions.
