Alloy GS 30
Designation
Description
Alloy GS 30 used: for the production of cast bar billets (LPZ), intended for subsequent remelting and casting parts blades and other shaped castings of gas turbine components.
Note
High-temperature casting Nickel-based alloy.
Standards
Chemical composition
Ni is the basis.
According to OST 1 90126-85 the chemical composition is given for the alloy ZhS30-VI. Boron, zirconium, cerium, calcium, lanthanum and yttrium are introduced by calculation and chemical analysis are not determined. In the alloy, the content of hafnium and zirconium is allowed to be determined in total in%. In the alloy, the mass fraction of vanadium is allowed up to 0.10%. Vanadium is introduced by calculation and chemical analysis is not determined. In the alloy, the presence of concomitant rare earth metals: neodymium, gadolinium, praseodymium and others in an amount not exceeding 0.015%, which are not determined by chemical analysis.
