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.
