E308L-16 Stainless Steel Welding Rods

Description:

It is a super low carbon stainless steel electrode with titanium calcium coating. It can be used for both alternating and direct current. Due to low sugar content, it can resist intercrystalline corrosion caused by carbide precipitation when there is no stabilizer such as niobium and titanium.

USES:

The same type of stainless steel structure, composite steel and dissimilar steel used in the manufacture of synthetic fiber, petrochemical and other equipment can also be used in the welding of nuclear reactor pressure vessel inner wall transition layer and tower inner member.
