What is the maximum temperature that alloy33 material can withstand in 98% concentrated sulfuric acid?

Alloy 33 is a nickel-chromium-molybdenum-iron alloy with high corrosion resistance, commonly used in the chemical industry for equipment handling highly corrosive media. However, the specific temperature limits for corrosion resistance depend on various factors, including the specific composition of the alloy, the operating conditions, and any impurities present in the medium. For environments with 98% concentrated sulfuric acid, it is usually necessary to consult the corrosion resistance data for that alloy or directly contact the manufacturer to obtain accurate information. Based on your question, I do not have sufficient information to directly provide the maximum temperature that Alloy 33 can withstand in 98% concentrated sulfuric acid, as such data is usually determined through laboratory tests or experience from long-term industrial use. It is recommended to consult the material supplier or manufacturer for the specific temperature range resistance to chemical media. As for 321 stainless steel, it is an austenitic stainless steel containing titanium, and it offers better temperature and corrosion resistance compared to ordinary 304 stainless steel. 321 stainless steel performs well in a variety of chemical media, including sulfuric acid at certain concentrations and temperatures. Although 321 has a certain degree of corrosion resistance, it may not be ideal as a metal material in high-concentration sulfuric acid and high-temperature environments. When using it, an evaluation must be carried out based on specific conditions and its corrosion resistance data, especially in the presence of concentrated sulfuric acid. In short, for the use of these two materials in 98% sulfuric acid, it is necessary to conduct a specific analysis of the medium, temperature, pressure, and other environmental factors. In the absence of exact data, it is recommended to conduct corrosion resistance tests on the material or consult the material supplier to determine its suitability and obtain the best engineering design advice. .

ALLOY 33 is a nitrogen-containing nickel-chromium-molybdenum-copper alloy. Judging from the data table below, its resistance to sulfuric acid corrosion is fairly good. Products from abroad.
