Description
Rutile coated electrode for Duplex 22%Cr stainless steels
These alloys are finding widening application in the offshore oil/gas, chemical and petro-chemical process industries for their good resistance to stress corrosion cracking and pitting corrosion with typical pitting resistance equivalent number (PREN) of 35-36. The weld metal poses a high tensile and yield strength. Its rutile coating ensures excellent weldability in all positions, except for vertical down, and a high resistance to cracking providing smooth arc transfer.
