Overview

SIST EN 2831:2001 is a European standard developed by CEN that focuses on the assessment of hydrogen embrittlement in steels through a slow bending test method. This aerospace series standard is essential for evaluating the susceptibility of steel components subjected to chemical or electrolytic surface treatments that may introduce hydrogen. Additionally, it helps verify the recovery of initial ductility following de-embrittlement treatments. The standard is widely applicable in aerospace and metallurgical industries where steel integrity under hydrogen exposure is critical.

Key Topics

  • Hydrogen Embrittlement in Steels
    Hydrogen embrittlement is a phenomenon where steel loses its ductility and toughness due to the presence of hydrogen. This standard addresses the methods to detect and measure this condition effectively.

  • Test by Slow Bending Method
    The prescribed test involves the slow bending of steel samples to induce stress, allowing the identification of embrittlement caused by hydrogen infiltration. The procedure measures the loss of ductility and structural weaknesses.

  • Surface Treatment Implications
    Chemical and electrolytic surface treatments can introduce hydrogen into steel. SIST EN 2831:2001 provides a reliable test framework to evaluate steel performance after such treatments.

  • De-Embrittlement Verification
    Some steels undergo de-embrittlement treatments aimed at restoring ductility by removing hydrogen. This standard includes methods to confirm the success of these treatments.

Applications

  • Aerospace Industry
    Ensures that steel components used in aircraft and spacecraft maintain their mechanical properties despite exposure to hydrogen during manufacturing or operational processes.

  • Steel Manufacturing and Quality Control
    Used by steel producers and treatment facilities to assess the risk of hydrogen embrittlement and verify the effectiveness of treatment processes.

  • Surface Engineering Processes
    Important for industries utilizing plating, coating, or chemical surface modifications prone to hydrogen absorption.

  • Research and Development
    Supports development of new steel alloys and treatment methods resistant to hydrogen embrittlement.
