AWS E308-15
Chrome 19 Nickel 10 Stainless Steel Electrode
 Description:E308-15
is a low carbon chrome19nickel10 stainless steel electrode
with low hydrogen type coating. The deposited mental
has good mechanical properties and inter-crystalline
corrosion resistant properties. It should be connected
with negative polarity on DC and can be welded in all
position.
Application:Used
to weld the 0chrome 19nickel9 stainless steel structure
which is anticorrosive and work under 300 degree centigrade,
as well as some bad welding steel structure such as
high chrome steel, and the surface of the pile welding
stainless steel structure.
