NS333
NS333 is a solid solution strengthened nickel-base alloy strengthened by Mo, W and other elements. It has good oxidation resistance and corrosion resistance. The maximum allowable service temperature is up to 1180 ℃, and it has good strength below 980 ℃. It has good technological performance and is easy to form and weld. The superheat sensitivity of the alloy is very strong. When the temperature reaches 1250 ℃ or higher, the strength and corrosion resistance of the alloy will decrease.

NS333 is a solid solution strengthened nickel-base alloy strengthened by Mo, W and other elements. It has good oxidation resistance and corrosion resistance. The maximum allowable service temperature is up to 1180 ℃, and it has good strength below 980 ℃. It has good technological performance and is easy to form and weld. The superheat sensitivity of the alloy is very strong. When the temperature reaches 1250 ℃ or higher, the strength and corrosion resistance of the alloy will decrease. ☞ Excellent corrosion resistance in oxidizing and reducing corrosive media ☞ Excellent resistance to pitting, crevice corrosion and stress corrosion cracking Scope of application： NS333 alloy can be widely used in manufacturing chemical and petrochemical industries, organic chemical reaction processes containing chlorides, especially in polluted inorganic acids or solutions, organic acids containing seawater, and pollution control equipment or waste treatment equipment. Typical applications include： ☞Pulp and paper industry, such as dissolving and bleaching containers ☞Scrubbers and reheaters on combustion and flue gas desulfurization systems, and wet fans ☞Sulfuric acid cooler ☞Manufacturing and processing equipment of non-pure phosphoric acid ☞As a flame retardant alloy for high-pressure oxygen applications |
