Acetic acid is produced in large magnitudes. It is one of the most used organic acids and is widely occurred as contaminant in the process of other chemicals. Acetic acid is also used as a solvent in some organic reactions. So, it is important to understand its corrosive behaviour. Acetic acid is categorized as a … Continue reading Corrosion resistance of High performance metals alloys in Acetic Acid

Inconel 718 is sensitive to stress corrosion cracking in hot waters, in caustic solutions and in hot chloride solutions, comprising of hydrogen sulfide or acids. Many stress corrosion cracking studies performed for the aerospace plants are not relevant to the oil and gas plant applications of the specificity of conditions needed for stress corrosion cracking. … Continue reading Evaluation of Stress Corrosion cracking of Inconel 718 in oil and gas field

Inconel 625 is a popular nickel based superalloy for its durability, fabricability, weldability and excellent corrosion resistance. Its supreme and versatile corrosion resistance under diverse temperature and corrosive conditions is the main reason for its wide acceptance in chemical and other plant applications. Inconel alloy 625 is an austenitic solid solution strengthened NiCrMo alloy that … Continue reading How does Inconel 625 perform in diverse corrosive environments

Usually it is understood that pure metals are more resistant to environmental assisted cracking as compare to alloyed metals because pure metals have lower mechanical strength and high ductility. For instance, it is said that commercially pure nickel is not prone to stress corrosion cracking, until unless it is heavily cold processed at high temperatures … Continue reading Observation of Stress corrosion behaviour of Nickel based alloys

However it is chemically categorized as a weaker acid than hydrochloric or sulfuric acid, some materials are extremely corrosive more than even hydrofluoric acid. Use of gold and platinum are fully resistant to corrosion in aqueous solutions. The engineering materials that are significantly used in hydrofluoric acid owe their corrosion resistance to the development of … Continue reading Corrosion resistance behaviour of Nickel alloys in hydrofluoric acid

Inconel grades are high nickel alloys that are designed to resist corrosion specifically at the elevated points. They are recommended materials for use in sulfur-free media. Inconel alloys are suitable for use from cryogenic points to above 1200oF. They are widely used in the chemical units. Applications include heaters, stills, bubble towers, condensers for treatment … Continue reading How do Inconel alloys perform in varied service conditions?
