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.
