Hastelloy B3 is among the best nickel-based alloys that can be used today in industries that require materials that can endure highly corrosive chemicals and extreme temperatures. It is a highly resistant alloy in aggressive acids and in reducing environments and is commonly utilized in chemical processing, petrochemical facilities and pharmaceutical equipment.
To companies that demand high-performance alloys that they can rely on, a partnered Hastelloy B3 Exporter like Jay steel corporation means high-quality materials that would meet international standards. This paper describes the properties of Hastelloy B3, its chemical composition and its key uses in industry.
What is Hastelloy B3?
Hastelloy B3 is a high-performance nickel molybdenum alloy chemical resistance material that has been developed as a material to withstand harsh corrosive conditions. It is referred to as UNS N10675 alloy, and falls into the group of Hastelloy alloys, B-series.
This is a nickel-molybdenum alloy, with minor amounts of chromium, iron and others. It has a special composition that offers a good resistance to corrosion in non-oxidizing acids, especially hydrochloric acid.
Hastelloy B3 is a better thermal stable, welds better and is resistant to stress corrosion cracking compared to its predecessor Hastelloy B2, making it a favored material in challenging industrial applications.
Due to these merits, manufacturers and engineers tend to use products provided by a reputable Hastelloy B3 Exporter to achieve longevity and security of chemical processing equipment.
Chemical Composition of UNS N10675 Alloy
The high corrosion resistance of Hastelloy B3 is due to its controlled chemical composition. Typical composition includes:
- Nickel (Ni): Minimum 65%
- Molybdenum (Mo): 27–32%
- Iron (Fe): 1–3%
- Chromium (Cr): 1–3%
- Cobalt (Co): Up to 3%
Small amounts of Manganese, Silicon, Carbon and other trace elements.
Nickel is very resistant to corrosion and molybdenum increases the resistance to the reducing acids and corrosion due to chloride.
The combination creates excellent Hastelloy B3 hydrochloric acid resistance and makes it suitable in those environments where other alloys cannot resist.
Important Hastelloy B3 Properties.
1. Excellent Corrosion Resistance
The high resistance of the Hastelloy B3 to corrosive chemicals, especially to hydrochloric acid of all concentration and temperature, is one of the most important Hastelloy B3 properties.
The alloy, in addition to being good in:
- Sulfuric acid
- Acetic acid
- Formic acid
- Phosphoric acid
This renders it a perfect nickel molybdenum alloy chemical resistance solution in chemical plants and processing units.
2. High Protection against Hydrochloric Acid.
The strongest attribute of this alloy is that it has an Hastelloy B3 resistance to hydrochloric acid.
Hastelloy B3, in contrast to many other stainless steels or nickel alloys, is able to withstand structural integrity and corrosion resistance when exposed to a highly concentrated acid environment.
Due to this property, it is commonly applied in equipment that handles hydrochloric acid, like reactors and storage tanks.
3. Improved Thermal Stability
The other significant benefit of UNS N10675 alloy is that it has a better thermal stability than the previous B-type alloys.
The composition of the alloy reduces the formation of corrosive phases throughout the heating and enables the alloy to maintain its corrosion resistance following welding or fabrication.
This simplifies the manufacturing and producing of complex components by manufacturers and fabricators.
4. Resistance to Stress Corrosion Cracking
Hastelloy B3 has excellent stress corrosion resistance against stress corrosion cracking (SCC) in chloride environments.
This is a very important property in industries, where equipment is subjected to high pressure corrosive chemicals or high mechanical stress.
5. Good Mechanical Strength
Hastelloy B3 has typical mechanical properties of:
- High tensile strength
- Excellent ductility
- Good formability
Such properties enable the alloy to be easily produced in the form of bars, pipes, fittings, plates and other industrial elements.
