SAFE transport of hot gases and vapours at temperatures of
up to 850°C – this is a problem facing many manufacturers
of components for the process industry. The smart choice for
the solution is austenitic stainless steel 1.4550/347H.
To meet the increasing demand, Ugitech has added UGI®
4550 to its broad stainless portfolio, and is one of only three
suppliers in Europe.
Steam lines, superheater tubes and exhaust systems
in reciprocating engines and gas turbines are classic
applications for Ugitech’s UGI 4550. The addition of Niobium
makes the finished steel grades a well-adapted solution for
temperature ranges between 425°C and 850°C.
Compared to most austenitic materials, UGI 4550 inhibits
the formation of chromium carbide precipitates at the grain
boundaries and thus stops intergranular corrosion.
The stainless product is optimum for parts for which
treatment of the material after welding is not feasible, such
as expansion joints and equipment for chemical processing
at high temperatures. UGI 4550 is also readily formed at room
temperature and is very easy to weld.
This means no hot cracking after welding. Good creep
resistance (resilience against temperature-dependent
deformation) and resistance to atmospheric corrosion and
oxidation at high temperatures further increase process
reliability.
Ugitech offers UGI 4550 in a wide range of dimensions: from
steel bar with a diameter of 130mm to ultrafine 16µm in
diameter.
The steel product is annealed or cold drawn to the required
mechanical properties. The minimum order quantity at
Ugitech is one ton for drawn steel bar and even lower for
drawn wire.
Ugitech is always able to deliver rapidly because the steel mill
is equipped with 40t melting furnaces.
