Application and Properties: |
Basic type electrode for
welding creep resistant steels. Weld metal matches the
composition of steel grade 12 CrMo19 5 featuring equal
resistance to high-pressure hydrogen attack, creep
resistance and creep rupture strenght. Typical
applications are : petrochemical proces plants,
hydrocrackers in chemical industries. Suitable to use in
pressure vessels and boilers subject to operating
temperatures up to 600°C. Preheating, interpass
temperature and post weld heat treatment should be done
in accordance with base metal to be welded. |
