Product Description
NS321 Alloy is a titanium-stabilized austenitic stainless steel known for its excellent resistance to intergranular corrosion, particularly after exposure to temperatures in the range of 427°C to 816°C (800°F to 1500°F). This alloy is well-suited for applications requiring high-temperature stability and resistance to oxidation and scaling.
Composition
NS321 Alloy primarily consists of:
- Nickel (Ni): 9 - 12%
- Chromium (Cr): 17 - 19%
- Carbon (C): ≤ 0.08%
- Manganese (Mn): ≤ 2%
- Silicon (Si): ≤ 0.75%
- Phosphorus (P): ≤ 0.045%
- Sulfur (S): ≤ 0.03%
- Titanium (Ti): 5x(C+N) min - 0.7%
- Iron (Fe): Balance
High-Temperature Resistance
NS321 Alloy is designed to withstand prolonged exposure to high temperatures without compromising its mechanical properties. The addition of titanium in the alloy helps stabilize the material, preventing carbide precipitation, which can lead to intergranular corrosion.
Corrosion Resistance
This alloy exhibits excellent resistance to oxidation and scaling, even at temperatures up to 870°C (1600°F). It is also highly resistant to corrosion in a wide range of acidic and alkaline environments, making it suitable for chemical processing and power generation applications.
Mechanical Properties
NS321 Alloy maintains good mechanical strength and toughness at both low and high temperatures. Its tensile strength, yield strength, and elongation characteristics make it a reliable choice for components exposed to significant mechanical stress.
Fabrication and Weldability
NS321 Alloy is known for its good weldability and formability. It can be easily welded using standard welding techniques without the need for post-weld heat treatment. This makes it ideal for the fabrication of complex components and structures.
Applications
- Aerospace: Exhaust manifolds, jet engine components, high-temperature fasteners
- Chemical Processing: Heat exchangers, pressure vessels, reactor components
- Power Generation: Boiler tubes, superheater tubes, steam piping
- Oil and Gas: Refinery equipment, offshore platforms, heat exchangers
Summary
NS321 Alloy is a versatile stainless steel that combines high-temperature stability, excellent corrosion resistance, and good mechanical properties. Its ability to resist intergranular corrosion after exposure to high temperatures makes it an ideal choice for a wide range of demanding industrial applications.
