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?

The new face of oil and gas discovery will be with deep wells, specifically in deepwater. As compared to shallow wells, deep wells normally need high performance nickel base alloys. Wells are classified as sweet or sour. Sweet wells are just mildly corrosive, whilst sour wells are extremely corrosive. Sour wells contain hydrogen sulfide, carbon … Continue reading Performance of high functional nickel based super alloys in sour oil and gas conditions
