GH2747
Introduction
GH2747 is a Fe-Ni-Cr based precipitation hardening superalloy. After solution treated, It could work in temperature range of 1100-1250°C for long term and up to 1300°C for short time.
The alloy has good strength, structure stability, excellent resistance to oxidation and corrosion. Main forms of product are rod, plate, pipe, wire and forging.
