ASTM A954 Grade 5S 10S 40S 80S Alloy Steel Pipe: Austenitic Chromium-Nickel-Silicon Alloy Steel Seamless Pipe for General Purpose
Material
ASTM A954 is a specification for austenitic chromium-nickel-silicon alloy steel seamless pipes. These pipes are designed for general-purpose applications and are known for their excellent corrosion resistance, high strength, and good ductility. The alloying elements contribute to the material's overall performance, making it suitable for various industrial applications.
Specification
The ASTM A954 specification covers seamless and welded austenitic chromium-nickel-silicon alloy steel pipes. The grades within this specification include Grade 5S, 10S, 40S, and 80S, which differ primarily in their wall thickness and mechanical properties.
Key Features
- Corrosion Resistance: Excellent resistance to oxidation and corrosion.
- High Strength: Suitable for high-pressure applications.
- Ductility: Good formability and weldability.
- Temperature Resistance: Performs well in high-temperature environments.

Steel Grade
The ASTM A954 specification includes several grades, each tailored for specific applications and performance requirements. The grades are designated as Grade 5S, 10S, 40S, and 80S, with increasing strength and wall thickness.
Application
The ASTM A954 alloy steel pipes are widely used in various industries, including:
- Oil and Gas: For pipelines and pressure vessels.
- Chemical Processing: In reactors and heat exchangers.
- Power Generation: For steam and gas turbines.
- Food and Beverage: In sanitary applications.
Possible Alternative Grades
While ASTM A954 is a specific standard, there are alternative grades that may be considered based on application requirements:
- ASTM A312: Standard for seamless and welded austenitic stainless steel pipes.
- ASTM A213: Covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes.
- ASTM A790: Standard for duplex stainless steel pipes.
