LOW HEAT INPUT WELDING ALLOYS
RASI WE -18
A Chromium - Nickel - Manganese Alloy Austenitic Electrode for joining dissimilar steels and for buttering layer application.
|
|
CHARACTERISTICS
RASI WE- 18 is a stainless steel electrode depositing an austenitic alloy of
chromium - Nickel - Manganese. The weld metal possesses high strength and
superb toughness even at minus 100oC.
Resists scaling upto 800oC work
hardens under impact. Usable as a surfacing alloy for anti - wear
properties. The electrode coating is carefully studied and chosen to achieve
very low hydrogen level in the deposited alloy, easily disposable slag,
finely rippled flat bead profile and low spatter. |
|
APPLICATIONS
Joins high alloyed steel with mild steel or low alloy steels and
welded joints between high manganese steel. As shock absorbing buffer on
armour plate steels prior to surfacing with hard alloys. Anti - wear layer
or rails, shunt points. The alloy workhardness to about 450BHN. The high
manganese in the alloy enhances toughness while welding nickel based steels. |
