Product Description

GH3128 seamless tubes represent a breakthrough in nickel-chromium-tungsten superalloy technology, specifically engineered to meet the demands of modern high-temperature fluid management systems. With a unique composition of 20% chromium, 8% tungsten, and balanced nickel, this alloy delivers unparalleled performance in oxidizing and carburizing environments up to 1200°C (2192°F).
 

Key Performance Features:

Oxidation Resistance: Forms a stable Al2O3-Cr2O3 protective layer, reducing oxidation rates by 70% compared to conventional alloys

Thermal Fatigue Resistance: Withstands 10,000+ thermal cycles between 20°C and 1100°C without cracking

Creep Strength: Maintains 90% of room temperature tensile strength at 950°C
 

Performance Advantages

• Thermal Cycling: 3x longer service life than Haynes 230 in cyclic oxidation tests

• Corrosion Resistance: Withstands 1000h in 90% N2-10% H2 at 1100°C with <0.1mm penetration

• Flow Efficiency: 25% lower pressure drop compared to ceramic alternatives

• Temperature Range: Continuous operation from -196°C to 1200°C
