    ASTM A928 UNS S32750 CL1 Super Duplex Stainless Steel Pipe EFW Welded Pipe

    ASTM A928 UNS S32750 Class 1 Super Duplex Stainless Steel EFW Pipe


    ASTM A928 is essential for industries requiring high strength and exceptional corrosion resistance in welded pipes. This specification covers five classes of duplex steel pipes, each with specific welding and radiography requirements. Pipes are commonly used in industries like oil and gas, chemical processing, marine environments, and power generation due to its excellent performance in corrosive and high-stress applications.

    Here are the main differences between ASTM A790 and ASTM A928
    ASTM A790

    1. Scope:

      • Covers welded and seamless ferritic-austenitic (duplex) stainless steel pipe intended primarily for use in pressure applications.

    2. Material Grades:

      • Focuses on specific grades (e.g., UNS S31803, UNS S32205) that typically have a higher yield strength and are compatible with higher pressures and temperatures.

    3. Applications:

      • Commonly used in oil and gas industries, chemical processing, and other pressure vessel applications where strength and corrosion resistance under pressure are critical.

    4. Testing Requirements:

      • Emphasizes rigorous testing for mechanical properties, such as yield strength and tensile strength, ensuring the pipe can withstand high-pressure conditions.

    ASTM A928

    1. Scope:

      • Specifically focuses on welded pipe made from duplex stainless steel for applications requiring corrosion resistance but may not involve the same pressure requirements as A790.

    2. Material Classes:

      • Divided into five classes (as previously mentioned), which offer various compositions and mechanical properties tailored to different applications.

    3. Applications:

      • Generally suited for less demanding environments where resistance to pitting and stress corrosion cracking is a priority, such as in certain chemical environments or marine applications.

    4. Testing Requirements:

      • While still requiring mechanical property evaluations, the focus is more on specific corrosion resistance tests rather than just high-pressure performance.
