machining and welding
·Cold working: suitable for cold drawing and cold rolling, which can increase strength.
·Hot processing: It should be carried out between 950-1200°C.
·welding: suitable for TIG and MIG welding, solution heat treatment is recommended after welding to ensure the best corrosion resistance.
Application
·Chemical equipment: used for storage tanks and pipelines in strong acid and alkali environments.
·oil industry: used in offshore platforms and oil refining equipment.
·Marine engineering: suitable for seawater desalination device and marine structure.
·pollution control equipment: used for key components in flue gas desulfurization plants.
Cornifer 926 alloys are available in different shapes and sizes, including plates, bars, wires and forgings.
