A specially formulated electrode which yields an Inconel type deposit that does not require
any special post-weld heat treatment to develop its optimum properties.
The weld deposit possesses an excellent ability to resist corrosion
and oxidation at high temperatures in applications such as furnace components
and reactor vessels. It shows excellent toughness at
cryogenic temperatures (0 upto -269 C ). Weld deposit gives tough
joints and also used for surfacing on heat resistant Cr and CrNi steels/cast steel grades and Ni-base alloys.

It is a special high recovery electrode depositing a fully austenitic
weld metal, with exceptionally high corrosion resistance to a variety of industrial acids.
It is well suited for joining and hardfacing on the same or similar stabilized
or non-stabilized, fully austenitic and molybdenium and copper based cast steels. For joining the base
materials mentioned above, or as an overlay, in phosphoric acid and sulphuric acid plants,
the weld metal has excellent corrosion resistance against many organic acids also.
