Product Description

Product Description

 

Introduction

LORK is a alloy manufacturer with 20 years of manufacturing experience.
 

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.

GH2747 Super Alloy Plate Applications
 

GH2747 has been used to make high-temperature anti-oxidation components in aviation and aerospace engine combustion chambers and afterburners. It is also used to make various industrial furnace rollers, transmission devices, thermocouple sleeves and other heat-resistant components. It is especially suitable for high-temperature anti-oxidation device parts in petrochemical, nuclear energy, metallurgy and other fields.
