Hitachi Metals offers Hercunite-S heat-resistant steel casting for exhaust systems to improve fuel economy and reduce CO2 emissions. With increasing demand for heat-resistant casting that withstands high-temperature exhaust gases from turbochargers, the Hercunite-S Series is a next-generation, downsized design that also meets higher fuel economy standards. Applications include exhaust manifolds, turbine housings, and exhaust manifold-integrated turbine housings. The series operates over a wide temperature range up to 1050°C (1922°F) and provides the correct shape for casting using the company’s computer-aided design and rig-burner test systems. Castings contribute to improved fuel economy and cleaner exhaust gases and are geared toward high-temperature combustion of engines with low-alloy, heat-resistant cast steel.
