摘要

Exhaust gas turbine comprises a running wheel which rotates in a turbine housing (1) having a spiral-like inlet channel (13) connected to an annular chamber. A guiding mesh (9) can be pushed into the annular chamber using a sliding sleeve. The guiding mesh is made from a cast steel containing (in wt.%) = 0.2 C, 1.5-2.5 Si, = 2.00 Mn, = 0.045 P, = 0.03 S, 24.0-26.0 Cr, 19-22 Ni and = 5 W.
