湖南Sanicro 69山特維克ENiCrFe-7鎳基焊條
Sanicro 69 是一種堿性藥皮焊條，用于大多數(shù)低合金鋼和不銹鋼上耐腐蝕堆焊。它還用于合金 690 型的合金，例如
Sanicro 69 和異種接頭的焊接。
該焊條具有優(yōu)良的焊接性能，非常適合接頭焊接以及堆焊。
STANDARDS
– ISO 14172: Ni 6152
– AWS A5.11/ASME SFA-5.11: ENiCrFe-7
APPLICATIONS
It is used for welding of alloys of Alloy 690 type (e.g. Sanicro 69) and dissimilar joints. It is also used for overlaywelding in the nuclear industry used primarily for steam generators in nuclear power plants (PWR). For thisapplication the material is characterized by extremely high stress corrosion resistance in primary side PWR waterconditions. Sanicro 69 also has improved pitting resistance in chloride containing solutions compared to alloy 600.
Sanicro 69 is characterized by excellent resistance to nitric acid. Furthermore, the material shows very goodresistance to high temperature oxidation.
