16.8.2
Description
Rod for base materials in stainless steel for high temperatures
Rod suitable for 3XXH stainless steels in high temperature applications up to approximately 800 °C. The controlled composition ensures good hot ductility properties and high resistance to thermal embrittlement from intermetallic phases. The ferrite content <5 FN ensures good toughness. Typical applications include furnace parts and components for the petrochemical, chemical, and energy production sectors. The filler metal can be used both in the as-welded condition and after solution treatment, making it suitable for welding thick base metals 347H/321H to avoid operational issues.
