600H Special Material Flanges in Various Industries with Material for Secure Connections​

Manufactured from Inconel 600H superalloy (UNS N06601), flanges are designed for extreme high temperature, pressure and corrosive environments and are ideal for the petrochemical, nuclear, aerospace and heat treatment industries. Its optimized carbon content (0.05-0.10%) and Nichro-based alloy (Ni≥72%, Cr 14-17%) structure give it excellent creep resistance (up to 1177°C/2150°F continuous operating temperature) and oxidation resistance, ensuring zero leakage sealing in molten salts, sulfides and high-temperature steam. Ensure the absolute safety of critical pipeline.

Core Benefits:

✅ Unmatched high-temperature performanceCreep and oxidation resistance: In ethylene cracking furnaces, gas turbine combustion chambers, etc., it can withstand high temperatures of 980°C+ for a long time, and its oxidation resistance far exceeds that of traditional stainless steels (such as 304H/316H).Thermal fatigue resistance: Adapt to frequent thermal cycles (such as heat treatment furnace doors, annealing equipment) to avoid embrittlement and deformation of materials.

✅ Corrosion and carburizing protectionCarburizing/nitriding resistance: Resists hydrocarbon attack in carburizing furnaces and ammonia decomposition units to extend equipment life.Corrosion resistance: Excellent resistance to alkaline molten salts, dry chlorine and weak acid media (such as phosphoric acid), suitable for alkali metal treatment and nuclear reactor cooling systems.

✅ Mechanical strength and reliabilityUltra-high strength: Tensile strength of ≥550 MPa at room temperature, excellent toughness at high temperatures, suitable for Class 150 to 2500 high pressure systems.Sealing stability: Precision machined flange face (RF/RTJ/FF), matching ASME B16.5 standard, to ensure air tightness under high temperature and high pressure.

✅ Global compliance and traceabilityComplies with ASTM B564, ASME SB-564, EN 1092-1 and PED 2014/68/EU standards to support the demanding needs of nuclear power (ASME III certification) and aerospace (AMS 5666).
