EN 13835 GGL‑NiCr 30/3: High‑Temperature, Corrosion‑Resistant Cast Iron for Pumps, Boilers, and Turbochargers

GGL NiCr 30 3 is to 800 °C heat and thermal shock-steadily, well corrosion resistant with increased temperatures, particularly erosion steady in saturated steam and salt dredging, middle thermal expansion. The material is comparable to UNS F 41004 with US. Application: For pumps, boiler, valves, filter parts, exit gas lines, turbocharger housings.
