Features & Applications
Its nominal deposited efficiency is about 110%. The weld metal shows excellent low
temperature toughness and high crack resistance. It is widely used in important structures
fabricated by equivalent tensile strength mild steels or low ally steels such as ships, boilers,
high pressure vessels, bridges, skyscrapers, offshore drilling platforms, nuclear power plants
and so on. It has been appointed to be honor consumables by almost all nuclear power
projects in China due to its faithworthy quality.
