Description:
TP347H is a high carbon austenitic chromium stainless steel. Found in
applications that demand high temperature resistance, other major
design features include: Similar resistance and corrosion
protection as Alloy 304. Used for heavy welded equipment when
annealing is not possible.
TP347H is type of precipitation-hardened steels. It possesses many same
properties and features of TP347 stainless steel. In addition to
its higher carbon content, TP347H is stabilized with an addition of
columbium. Because of its elevated resistance to corrosion, TP347H
is usually applied in high stress, high corrosion environments
where exposure tends to be severe. This steel shows high
workability under common welding techniques. It can be treated with
heat, however, it will not respond. Only cold working is sufficient
to increase TP347H’s toughness and strength.
