Aftermarket HE431VTi Turbine Housing for Cummins Turbo 4036847

The Turbocharger Turbine Housing is an important part of the turbocharger. The main function of the turbine housing is to collect the exhaust gases from the engine, and directs them through a volute (passage) into the turbine wheel and causing it to spin. As a result of this, the compressor wheel rotates by the shaft connected with the turbine wheel. The turbine housings are also referred to as the “hot side” of the turbo because of their continuous exposure to hot exhaust gas.

Our Turbine housings' Casting Materials include:
Ductile Iron (QT450-10): The continuous heat resistance is less than 650 degrees Celsius, but due to its mature casting process and relatively low casting cost, ductile iron has become the most commonly used cast iron material for the production of the turbine housing.
Medium Silicon Molybdenum Ductile Iron：0.3%-0.6% molybdenum is added to commonly used nodular cast iron，molybdenum increases the strength and hardness of the cast irons, Heat resistance is better than ordinary nodular ductile iron QT450.
Medium silicon molybdenum nickel ductile iron：0.6%-1% nickel is added to the medium silicon molybdenum ductile iron, which has better heat resistance than ordinary ductile iron QT450.
High-Nickel Ductile Iron (D5S): 34% Nickel, heat-resistant ductile iron, Used to manufacture superchargers with high-temperature resistance requirements, and the continuous high-temperature resistance can reach 760 degrees Celsius or more.
