Better Quality Better Service

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

Nickel based alloys containing chromium, molybdenum, tungsten and other elements are commonly used for equipment production in the petrochemical, chemical process and power plants due to their supreme corrosion resistance in the oxidizing and reducing conditions. The availability of sufficient chromium content enhances the development of passive barrier oxide layer of Cr2O3 on the surface … Continue reading How nickel based alloys perform against localized corrosion

Acid solutions are widely used in chemical industry to eliminate mill scales from metallic surface. The inclusion of inhibitors suitable secures the metal against an acid corrosion. Usually acid inhibitors are organic compounds comprising of nitrogen, oxygen and sulfur. These compounds are adsorbed on the metallic surface blocking the active corrosion sites. Due to toxicity … Continue reading Corrosion behaviour of nickel and its alloys in HCl and its prevention by natural rosemary oil

Nickel-Chromium-Molybdneum alloys were selected as suitable materials for nuclear waste containers as they provide outstanding resistance to localized corrosion in conditions that may occur at the permanent repository site. It was crucial to determine if prolong exposure to low temperatures would be harmful to the resistance property of Hastelloy C22 , C4 and C276 alloys … Continue reading Which alloy is the best fit for nuclear waste containers
