Description

Because of its 13.5% chromium and 3% molybdenum content, WFN has a high tempering resistance up to around 450 °C, as well as high-temperature hardness and good corrosion resistance. The thermal expansi- on coefficient is adjusted to that of steel through the 1% aluminium alloy addition. Lower stresses thereby occur when non-permanent and permanent joints are heated, reducing the risk of cracking.
