crevice corrosion

Nickel based alloys are used in a wide range of applications as corrosion resistant materials, heating element and also creep resistant materials. Other applications include construction materials. These alloys can create a security layer in some conditions to provide corrosion resistance. Although, they may be affected in environments comprising significant magnitudes of chloride or halide … Continue reading Effect of pH and temperature on crevice corrosion of nickel based alloys

It is true to state that seawater is probably the most common example of aqueous salt solution. It will not just encounter with the marine based transportation and offshore related oil rigs, but it can also work well as coolant in some of the coastal facilities. Now, there are some materials used for the industrial … Continue reading Proficient Use Of Hastelloy C22 In Aqueous Solutions

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

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

The oil and gas plants often choose to configure stainless steel tubing in the instrumentation and sensor components in addition of chemicals, hydraulic lines, impulse lines and various utility applications for a broad range of temperature limits, pressure and flow values. It is found that stainless steel 316 tubing offers moderate corrosion resistance in the … Continue reading Pitting and crevice corrosion of materials in seawater

The duplex steels offer an excellent range of corrosion resistance in the diverse media. Following is the brief explanation of their resistance in the variety of application conditions. Uniform Corrosion: Uniform corrosion is featured by even attack on the steel surface that comes in contact of the attacking media. The prevention of corrosion is assumed … Continue reading Corrosion resistance of duplex stainless steels
