LOW HEAT INPUT WELDING ALLOYS
RASI WE -18T A Chromium -
Nickel - Manganese Alloy fully Austenitic Electrode for high resistance to
corrosion and thermal Shock resistance.
CHARACTERISTICS
RASI WE - 18 T is a stainless steel electrode with low spatter, self
disposing slag, finely rippled extra ordinary weld metal. Resists scaling
and shock at ordinary and elevated temperatures up to 800oC
Possesses work hard-ening properties. Ease of welding is an advantage, Radiographics quality tough crack - resistant deposit. High welding stresses
can be absorbed by the weld deposit.
APPLICATIONS
Weld joins alloyed and unalloyed steels, manganese alloy steels and
between manganese alloy steel and several other steel grades. The deposit
alloy cold hardens under impact. Hence, the electrode may be used for weld
surfacing of cold - hardening components such as curved sections of RAilway
lines, Shunt points, Crusher cones. Also serves as a buffer layer for
absorbing shocks after hard surfacing on above mentioned steels.
