DESCRIPTION
VSS-318 is a lime-titania type stainless steel electrode which produces perfect austenitic structures. It has excellent usability and weldability. As the weld metal contains Mo, the deposited metal has excellent corrosion resistibility oxidizing acid and non-oxidizing acid such as sulfuric acid, etc. As the deposited metal also contains Nb, it is excellent resistance to intergranular corrosion and has no precipitation of chromium carbide in the weld metal.
APPLICATIONS
Welding of chemical plant which is exposed to non-oxidizing acid such as sulfuric acid, sulfurous acid, phosphoric acid, etc.
Welding of AlSl316 which required to prevent precipitation of chromium carbide in the welding.
INSTRUCTIONS FOR WELDING
- Keep the arc length as short as possible.
- Choose the welding current within the range stated in the table below.
