Caustic Corrosion - an overview ScienceDirect Topics

Feb 10, 2011 · According to the pH monitoring data of the process water, especially at site II and III, the QO/DS heat exchanger tubes had been subjected to an over alkaline (pH > 9.5, even reached 11.5) environment for a long time. Consequently, caustic corrosion (called caustic embrittlement more accurately, a specific kind of stress corrosion cracking) was engendered on the carbon steel tubes Comparing ium, Nickel Alloy, Aluminum - Salem TubeOct 26, 2017 · Salem Tube is a steel tubing manufacturer headquartered in Greenville, PA. We offer fully integrated tubing solutions for complex projects, critical applications, and special customer requests. Our portfolio includes all materials from carbon steel to titanium but our main specialty is stainless steel tubing and high nickel alloys. Corrosion Resistant Metals Materials Selection Guide For Fighting:General Corrosion; Localized Corrosion; Stress Corrosion Cracking; Sour Gas Cracking . Alloy C-276 Nickel Alloys. Alloy C-276 (Hastelloy ® C-276) contains nickel, molybdenum, and chromium. Its high molybdenum content makes it exceptionally resistant to pitting and crevice corrosion, and it is one of only a few materials that can withstand the corrosive effects of wet chlorine

Corrosion of High-Alloy Superheater Tubes in a Coastal

Apr 01, 2008 · Despite the favorable ranking, the Alloy 625 weld overlay can corrode by active oxidation at an appreciable rate (0.45 mm/y [18 mpy]) under existing boiler operating conditions. A promising corrosion control strategy involves reducing the steam temperatures in the outlet tubes of the three superheater sections to below 500°C. Description of Boiler Tube Grades & Recommended Uses A 9-chromium-1 molybdenum alloy, T9 offers very good corrosion resistance with good high-temperature strength. It also has good oxidation resistance and can be used to 1200F maximum. Some times T9 is an adequate substitute for the more expensive stainless grades.

Evaluation of High Temperature Corrosion Resistance of

Jun 01, 2016 · Abstract The purpose of the paper was to evaluate the resistance to high temperature corrosion of laser welded joints of finned tubes made of austenitic steel (304,304H) and nickel alloys (Inconel 600, Inconel 625). The scope of the paper covered the performance of corrosion resistance tests in the atmosphere of simulated exhaust gases of the following chemical composition:0.2% HCl, High Temperature Alloys, NITRONIC, INCONEL, HASTELLOYINCONEL ® alloy 625 (UNS N06625) Ni 61.0, Cr 21.5 Mo 9.0, Nb+Ta 3.6 High strength and toughness from cryogenic temperatures to 1800 degrees F (980 degrees C), good oxidation resistance, exceptional fatigue strength, and good corrosion resistance. Inconel 625:Properties, Applications and Production Inconel 625 is a high-performance nickel-chromium-molybdenum alloy known for its high level of strength, temperature resistance, and corrosion resistance. This superalloy is composed mainly of nickel (58% min.) followed by chromium, and molybdenum, niobium, iron, tantalum, cobalt, and trace amounts of manganese, silicon, aluminium, and titanium.

Metals & Alloys for High-Temperature Services

Tungsten is a steel-grey or silver-white metal that possesses high hardness levels, a high melting point and a resistance to air erosion at room temperature. As a refractory metal, it has a high resistance to heat and a high melting point. Tungsten can be used as Nickel Alloy 625 Tubes On Continental Steel & Tube Co.Combining high strength properties with ease of fabrication, Nickel Alloy 625 and Inconel® 625 is a popular nickel-chromium alloy used in nuclear power production, marine engineering, and aerospace. With the addition of molybdenum and niobium, Nickel Alloy 625 Pitting and crevice corrosion of offshore stainless steel Of these alloys, 625 and C-276 have demonstrated excellent resistance to localised corrosion. Ferritic alloys such as Sea-Cure and AL29-4C are resistant to attack by aqueous chloride solutions and are primarily used as heat exchanger tubing.

Alloy 625 Grade 1 Corrosion Materials

  • DescriptionIndustries and ApplicationsResistance to CorrosionFabrication and Heat TreatmentCommon Trade NamesAlloy 625 has good resistance to oxidation and scaling at high temperatures. At 1800°F, scaling resistance becomes a significant factor in service. It is superior to many other high temperature alloys under cyclic heating and cooling conditions. The combination of the alloyed elements in alloy 625 enables it to withstand a wide variety of severe corrosive environments. There is almost no attack in mild environments, such as fresh and seawater, neutral pH environments, and alkaline media.
