A turbine housing (13) for a radial flow turbine, particularly a turbine used in an exhaust gas turbocharger. The housing has a general volute shape with a substantially annular part extending around the turbine axis and an inlet duct (20) extending therefrom. The inlet duct (20) has a first wall facing part of the outer surface of the annular part of the housing, a pair of spaced webs (44) extending from the outer surface of the circular part of the housing to the first wall, the webs defining a valley (45) therebetween. The arrangement renders the housing stiff er and less prone to fatigue cracking.
