1. Nickel based alloy Introduction
- Incoloy alloy is a nickel based corrosion-resistant alloy of the iron chromium series. It has good corrosion resistance in reducing and oxidizing acids, as well as good resistance to stress corrosion cracking, pitting, and crevice corrosion. Commonly used materials in chemistry, petrochemicals, nuclear industry, and rare metal extraction include incoloy800, incoloy825, incoloy926, etc.
- Inconel alloy is a nickel, chromium, and iron solution strengthening alloy with excellent high-temperature corrosion resistance and oxidation resistance, as well as excellent cold and hot processing and welding performance. It is widely used in aviation, chemical, paper industry, and other fields. Commonly used ones include inconel600 inconel601 inconel625 inconel617 inconel718 inconelx750, etc.
- Hastelloy alloy is a nickel based corrosion-resistant and high-temperature alloy, mainly divided into two categories: nickel chromium alloy and nickel chromium molybdenum alloy. It has good corrosion resistance and thermal stability, and is commonly used in aviation, petrochemical, chemical fields, etc. Commonly used include Hastelloy C276, Hastelloy C22, Hastelloy b2, Hastelloy b3, Hastelloy C4, Haynes 230, Haynes 188, etc.
2. Hastelloy C276 Pipe Fittings
The Hastelloy C-276 alloy demonstrates unparalleled corrosion resistance to a vast array of corrosive media, operating effectively in both oxidation and reduction conditions. It boasts superior resilience against point corrosion, crevice corrosion, and stress corrosion cracking, ensuring durability and stability in harsh environments. This alloy is ideally suited for various chemical process industries that involve oxidizing and reducing media, making it a versatile material choice.
The high content of molybdenum and chromium in Hastelloy C-276 significantly enhances its resistance to chloride ion erosion, a common issue in corrosive environments. Furthermore, the addition of the tungsten element further elevates its corrosion resistance, ensuring superior performance in extreme conditions.
Notably, Hastelloy C-276 is one of the rare materials capable of enduring corrosion caused by humid chlorine gas, hypochlorite, and chlorine dioxide solutions. This makes it a reliable choice for applications involving these highly corrosive chemicals.
Additionally, this alloy exhibits remarkable corrosion resistance to high concentrations of chloride solutions, including iron chloride and copper chloride. This property further expands its applicability in industries where such solutions are commonly used. Overall, Hastelloy C-276 is a superior alloy choice for applications requiring exceptional corrosion resistance in challenging environments.
