Why EN25 Powers Your Piping Dreams

    EN25 is a high-strength nickel-chromium-molybdenum steel that is an excellent choice for stainless steel pipes and fittings. With a tensile strength of 930-1080 MPa, it excels in severe conditions. It is tough enough to meet the requirements of large pipe fittings and is pre-hardened and tempered for improved mechanical properties.

    Core Advantages of EN25

    With a tensile strength of 1080 MPa, it ensures that stainless steel tubing remains hard under high pressure. Can withstand heavy loads in aerospace or industrial systems without buckling.

    It absorbs bumps and vibrations and stops oversized stainless steel fittings from cracking. Can keep pipes intact during handling or high-impact operations.

    Flaming or nitriding pushes its surface toughness to the limit, protecting fittings from wear and tear. Extends service life in harsh wear environments.

    For gears, shafts and stainless steel tubing in a wide range of industries. Its versatility shines in automotive, aerospace and energy applications with consistent reliability.
