In the realm of materials engineering, the demand for highly specialized and durable components is ever - increasing. Our Incoloy20/Incoloy28 capillary tubes are at the forefront of meeting these requirements, especially in the chemical and petrochemical industries. These capillary tubes are designed to withstand harsh chemical environments, high temperatures, and mechanical stresses, making them an ideal choice for a wide range of applications.
Incoloy20
Incoloy20 is a nickel - iron - chromium alloy, enriched with copper and molybdenum. The nickel content provides excellent resistance to chloride - induced stress corrosion cracking. Chromium, on the other hand, forms a passive chromium oxide layer on the surface of the alloy, protecting it from oxidation and corrosion in various acidic and alkaline media. The addition of copper enhances its resistance to sulfuric acid, while molybdenum improves its pitting and crevice corrosion resistance. Incoloy28
Incoloy28 is a high - performance alloy with a balanced composition of nickel, chromium, and molybdenum. The relatively high chromium content (around 27%) offers outstanding resistance to general corrosion in oxidizing environments. The nickel base provides good resistance to reducing acids, and the molybdenum addition significantly enhances its resistance to pitting and crevice corrosion, especially in chloride - containing media.
