gh3030(gh30)
The alloy is an early development of 80Ni-20Cr solution-strengthened superalloy, with simple chemical composition, satisfactory thermal strength and high plasticity below 800 °C, and good oxidation resistance, thermal fatigue, cold stamping and welding process performance. The alloy is single-phase austenite after solution treatment, and the structure is stable during use. It is mainly used for turbine engine combustion chamber parts that work below 800°C and other high-temperature parts that require oxidation resistance below 1100°C but bear little load.
Metallographic organizational structure
The alloy is a single-phase austenite structure with a small amount of TiC and Ti(CN) between the solid solution treatment at 1000 degrees Celsius.
Process performance
1. The alloy has good malleability, with a forging heating temperature of 1180 °C and a final forging of 900 °C.
2. The average grain size of the alloy is closely related to the deformation degree of the forging and the final forging temperature.
3. After heat treatment, the oxide scale on the surface of the parts can be removed by sand blowing or pickling.
Melting and casting processes
Electric arc furnace melting or electric arc furnace melting plus electroslag remelting or vacuum arc remelting, non-vacuum induction furnace plus electroslag melting or vacuum electric arc furnace remelting or vacuum duplex process.
Application overview and special requirements
The alloy has been tested in aero engines for a long time, and is mainly used for combustion chamber and afterburner parts, as well as casing mounting edges.

Our advantage
Quality Assurance: We take pride in our rigorous testing and quality control measures that ensure only the best materials reach our clients.
Advanced Technology: Our facilities are equipped with state-of-the-art technology for both standard and custom metal production.
Vast Inventory: We boast a comprehensive inventory that enables us to fulfill orders rapidly and efficiently.
Custom Fabrication: Our team of experts works closely with clients to provide bespoke solutions tailored to their specific needs.
Q: How can I pay my order?
A: We accept T/T, Western Union,Alibaba Online Payment to pay.
Q: Do you have any certificate?
A: We have passed ISO9001:2008，ISO14001OHSAS18001 and obtained CE certificate and BSCI certificate from UL.
Q: Why the model name of your machine same as the machine form other company?
A: Since these machines have long history and are very popular in the market, it may be indeed possible that some machine models are similar as others. What we may think is that the machine model does not make big difference. And the criteria for machines may depend on the technical support and quality of the machines.
Q: How about your warranty?
A: Our warranty is 12 months. Normally,the general after-sale service may be as below.
1) The technical support is permanent.
2) The paid spares parts could be provided at any time,
3) We have dealers in some countries to offer compensable service.
