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.
