Product features

GH4133B is a Ni-Cr-based precipitation-hardened wrought superalloy. GH4133B alloy is a modified version of 3 alloy with the addition of appropriate amounts of magnesium and zirconium. Both alloys are used at temperatures below 750°C and possess excellent comprehensive mechanical properties with high yield stthey exhibit good oxidation resistance, stable microstructure, and uniform fine grains; and are easy to hot work. In particular, GH4133B alloy improves the notch sensiivity of GH4133 alloy at temperatures below 750°C, significantly increasing the service life of the material and greatly enhancing its creep strength an

Application scope domain

GH4133B alloy has been used to manufacture important components such as turbine disks and load-bearing rings for various types of aero-engines, with satisfactory performance in mas production. This alloy is also suitable for manufacturing critical load-bearing components like turbine disks and working blades for aero-engines operating at temperatures below 750°C. Major productsinclude hot-rolled and forged bars, disk forgings, and ring forgings.
