GH3030 (EI435 / Nimonic 75) | China GB Standard High Temperature Alloy Supply
GH3030 (EI435 / Nimonic 75) | China GB Standard High Temperature Alloy Supply
GH3030 (Chinese GB standard) is an 8ONi-20Cr solid solution strengthened high-temperature alloy with performance comparable to Nimonic 75 (UNS N06075/El435), exhibiting excellent oxidation resistance and thermal stability up to 800℃. It is widely used in aerospace combustion chambers, afterburners, and heat-resistant industrial parts.
What is GH3030 material?
GH3030 is a high-temperature nickel-based superalloy primarily used in components requiring high oxidation resistance and thermal stability. Due to its excellent performance in high-temperature environments, GH3030 is widely used in the aerospace and power generation industries.

FAQ
Q: Can GH3030 directly replace Nimonic 75 in aircraft engine components?
A: Yes. GH3030 and Nimonic 75 have very similar nickel-chromium matrix and mechanical properties. It is widely used in combustion chamber liners, combustor components, and exhaust manifolds, and has the same service life below 800°C.
Q: Does GH3030 conform to the Russian EI435 (ЭИ435) standard?
A: Fully compliant. GH3030 was originally developed based on Russian EI435 (ЭИ435)/VZh98 technology. Its chemical composition and thermal strength are fully compatible with Soviet-designed aerospace and industrial equipment.
Q: What forms of GH3030 products can you provide?
A: As a comprehensive high-temperature alloy manufacturer, we offer:
Seamless tubing: Bright annealed or pickled surface treatment.
Round bars: Bright ground or precision stripped.
Sheet metal: Cold-rolled or hot-rolled, suitable for stamping.
Welding wire: Welding wire compatible with GH3030 assembly.
Q: How to verify material quality?
A: We provide complete traceability. In addition to our in-house factory test certificate (MTC), we also support inspections by third-party organizations such as SGS, TUV, or BV to verify the chemical and mechanical properties of the materials before shipment.
