GH3030 High-Temperature Alloy Plate (Ni-Cr-Fe Alloy) | Superior High-Temperature Strength & Oxidation Resistance

✓ Oxidation Resistance: Forms a stable Cr₂O₃ oxide layer at 1000°C (1832°F), reducing scaling by 90% vs. 321 stainless steel.

✓ Thermal Fatigue Strength: Withstands 10,000+ thermal cycles between 20°C–950°C (68°F–1742°F) without cracking.

✓ Rapid Fabrication: Cold-rolled plates with **±0.1mm thickness tolerance** and Ra ≤1.6μm surface finish for laser/plasma cutting.

✓ Weldability: Low carbon content (<0.08%) minimizes carbide precipitation; ER310 filler recommended for arc welding.

GH3030 High-Temperature Alloy Plate (Ni-Cr-Fe Alloy)

Engineered for extreme thermal environments, GH3030 high-temperature alloy plate combines a nickel-chromium-iron matrix (Ni-76%, Cr-20%, Fe-1.5%) to deliver exceptional oxidation resistance, thermal fatigue strength, and creep resistance up to 1000°C (1832°F). Certified to GB/T 14992, AMS 5542, and ASTM B168, this alloy outperforms conventional stainless steels in aerospace, gas turbine, and industrial furnace applications, offering 3x the lifespan of 310S stainless steel in cyclic thermal stress conditions.
