Today's Sharing on Special Materials Trio：
1.Specialty materials: Hastelloy C22, C276, Titanium, and their composite plates; Zirconium, Tantalum (The last two are very expensive and therefore rarely used.).
2.Corrosion Resistance of Special Materials:
Hastelloy owns good resistance to hydrochloric acid and is commonly used in the pharmaceutical industry.
Titanium can withstand certain levels of chloride ions and is frequently used in seawater desalination.
Tantalum is resistant to sulfuric and hydrochloric acids and is commonly used in acid concentration recovery.
Zirconium is often used in the acetic acid industry.
However, it is important to point out that the corrosion resistance of metal materials is greatly affected by temperature and concentration, and the relationship is non-linear. The material's corrosion resistance is particularly sensitive to temperature changes. Most corrosion data in China are point data, and it is difficult to find corrosion curves. All data can only be used as a reference.
3.Hydrofluoric acid presents a challenge, as almost no metal can withstand it. Non-metallic materials must be used, and it is crucial to avoid using enamel and fiberglass-containing materials. Designers often overlook the selection of materials for small parts, such as sight glass. The process must be well-controlled in terms of temperature and pressure or vacuum...
With over a decade of research on various high-corrosion-resistant materials, I have accumulated a certain amount of knowledge and hope to help you and your project better.
