Corrosion Resistance
WTI inserts are manufactured in 18/8 austenitic chromium/nickel
stainless steel and offer excellent corrosion resistance, preventing
adverse seizing and galling even at elevated temperatures. For applications
involving severe corrosive conditions or subject to the effects
of galvanic corrosion, additional surface coatings are available,
such as cadmium, zinc, aluminium, silver or molybdenum disulphide.
Temperature Range
Standard inserts, manufactured in 18/8 stainless steel are suitable
for operation within temperatures ranging from -160¨¬C to +420¨¬C
(-320¨¬F to + 800¨¬F).
For applications involving extreme and elevated temperatures wire
thread inserts can be manufactured in creep resistant nickel based
alloys.
Cost & Weight Benefits
Wire thread inserts are much lighter and less expensive than any
other equivalent thread insert. As a result of their compact size
they can generally be incorporated into existing designs where no
previous provision has been made. In many instances, because of
their mechanical strength benefits their introduction may result
in the use of thinner sections or lighter parent materials without
sacrificing thread strength.
Wear Resistance
Due to a combination of material hardness and brilliant surface
finish wire thread inserts create internal threads in which wear
due to thread friction is virtually eliminated. This is of particular
value in applications requiring repeated assembly & disassembly.
The low frictional coefficient ensures that virtually all of the
applied assembly torque is converted into clamping load. Thus providing
threads that stay tight.
