Description:
It is a super low carbon stainless steel electrode with titanium calcium coating. It can be used for both alternating and direct current. Because of its low carbon content, it can resist intercrystalline corrosion caused by carbide precipitation without stabilizer such as niobium and titanium.
Application:
It is used for the same type of stainless steel structure, composite steel and dissimilar steel in the equipment of synthetic fiber, petrochemical industry, etc.
