GH3030 Nimonic 75/EI435 Chemical Composition and Data Sheet
GH3030 (also known as Nimonic 75 or DIN 2.4630/2.4951) is a solid solution strengthened nickel-chromium based heat-resistant alloy, commonly used in high-temperature applications up to 1100°C. It exhibits excellent oxidation resistance, high plasticity below 800°C, and good cold forming and welding properties.
What are the equivalent materials for NIMONIC 75?
Other materials equivalent to NIMONIC 75 alloy include: DIN 2.4630 and DIN 2.4951.
1. Chemical composition of GH3030 Alloy
The stability of GH3030 in an oxidizing atmosphere at 800℃ stems from its precise Ni-Cr-Ti ratio. We employ a vacuum ion melting (VIM) + electroslag remelting (ESR) process to ensure ultra-low impurity content.
| Element | Nickel (Ni) | Chromium (Cr) | Titanium (Ti) | Iron (Fe) | Aluminum (Al) | Manganese (Mn) |
| Percentage | Balance (≥75.0) | 19.0 - 22.0 | 0.15 - 0.35 | ≤ 1.50 | ≤ 0.50 | ≤ 0.70 |
Silicon (Si): ≤ 0.80% | Phosphorus (P): ≤ 0.030% | Sulfur (S): ≤ 0.020%
Note: Precise Ti control prevents grain growth, a common failure point in inferior alloys.
2. Mechanical and physical properties of GH3030
GH3030 has high plasticity and low coefficient of thermal expansion, making it the gold standard for high-temperature non-load-bearing components.
| Mechanical & Physical Properties | Value |
|---|---|
| Tensile Strength (Rm) | ≥ 685 MPa (100 ksi) |
| Yield Strength (Rp 0.2) | ≥ 275 MPa (40 ksi) |
| Elongation (A5) | ≥ 35% (Ideal for deep drawing & forming) |
| Density | 8.4 g/cm³ |
| Melting Range | 1374°C - 1420°C |

FAQ
Q1: Does your GH3030 comply with the Russian ЭИ435-ВИ specification?
A: Yes. We offer GH3030-VI, which is the vacuum-melted version directly equivalent to ЭИ435-ВИ. It is specifically refined for critical aviation engine parts requiring higher purity and fatigue life.
Q2: Can I get high-temperature stress-rupture curves in the datasheet?
A: Our downloadable GH3030 Technical PDF includes complete oxidation curves, thermal conductivity data, and stress-rupture charts from 600°C up to 900°C.
Q3: Do you provide certification for nuclear or military use?
A: As a professional superalloy supplier, we provide EN 10204 3.1 Mill Test Certificates with every batch. For sensitive projects, we support third-party verification from SGS, TUV, and BV to confirm 100% compliance with your specific RFQ.
