HastelloyC-276 (Hastelloy) is a tungsten-nickel-chromium-molybdenum alloy with extremely low silicon-carbon content and is considered to be an all-around corrosion-resistant aluminum alloy. The key moisture-resistant chlorine, various air-oxidizing fluorides, isopropyl titanate solutions, hydrochloric acid and air-oxidizing salts, have good corrosion resistance in ultra-low temperature and standing temperature sulfuric acid. Therefore, in the past 30 years, it has been widely used in extremely corrosive natural environments such as chemical plants, petrochemicals, flue gas desulfurization, pulp and paper industry, and environmental protection.

Corrosion resistance

The aluminum alloy has the following characteristics: 1. It has good corrosion resistance to most corrosive substances under the two conditions of air oxidation and repair. ¢ÚIt has good resistance to pitting corrosion, void corrosion and intergranular corrosion. The higher content of Mo and Cr makes the aluminum alloy resistant to corrosion by chloride ion content, and the W element further improves the corrosion resistance. At the same time, Hastelloy C-276 aluminum alloy is one of the only types of raw materials that are resistant to wet chlorine, hypochlorite and chlorine dioxide saturated solutions. Ester solution has obvious corrosion resistance. It is one of the very few raw materials that can be used as a hot sulfuric acid saturated solution.

Alloy steel is a steel alloyed by adding a variety of elements with a total amount between 1.0% and 50% in order to improve its mechanical properties. Alloy steels are divided into two categories: low alloy steels and high alloy steels. The distinction between the two is debatable. Smith and Hashemi defined the difference as 4.0%, while Degarmo et al. defined the difference as 8.0%. Most commonly, the phrase “alloy steel” refers to low alloy steel.
