Nickel-Based Alloy Introduction
1. Incoloy Alloy Series: Incoloy alloys are nickel-based, corrosion-resistant alloys
primarily composed of iron and chromium. They exhibit strong
resistance to both reducing and oxidizing acids, alongside notable
resistance to stress corrosion cracking, pitting, and crevice
corrosion. This makes them ideal for use in fields such as
chemistry, petrochemicals, nuclear industry, and the extraction of
rare metals. Key materials in this series include Incoloy 800,
Incoloy 825, and Incoloy 926.
2. Inconel Alloy Series: Inconel alloys consist of nickel, chromium, and iron, and are
known for their solution strengthening capabilities. They offer
exceptional resistance to high-temperature corrosion and oxidation,
making them suitable for demanding environments. These alloys are
also noted for their excellent processing and welding capabilities,
both in cold and hot conditions. They are extensively used across
various sectors including aviation, chemical processing, and the
paper industry. Popular grades include Inconel 600, 601, 625, 617,
718, and X750.
3. Hastelloy Alloy Series: Hastelloy alloys are high-temperature, nickel-based alloys, split
into two main categories: nickel-chromium and
nickel-chromium-molybdenum alloys. These materials are known for
their superb corrosion resistance and thermal stability. Commonly
utilized in aviation, petrochemical, and chemical industries,
prominent Hastelloy grades include Hastelloy C276, C22, B2, B3, C4,
Haynes 230, and Haynes 188.
Incoloy 825 Pipe Fittings Overview
Material Specifications:
- Standard: ASTM B366 / B366M - 20, which outlines the specifications for
wrought nickel and nickel alloy fittings.
Composition and Properties:
- Incoloy 825 is crafted from a nickel-iron-chromium base, enriched with
elements such as molybdenum, copper, and titanium. This chemical
composition is engineered to deliver outstanding resistance against
numerous corrosive environments, surpassing that of Alloy 800,
particularly in terms of aqueous corrosion resistance.
These properties make Incoloy 825 an excellent choice for pipe
fittings in industries where high corrosion resistance is
essential, including oil and gas, chemical processing, and marine
applications.
