Hastelloy C-4

Product Overview
Hastelloy C-4 is an austenitic low-carbon nickel-molybdenum-chromium alloy, widely recognized for its excellent thermal stability and corrosion resistance, making it ideal for use in chemical industries and high-temperature environments. Its low carbon content significantly enhances its resistance to intergranular corrosion and improves weldability. The alloy maintains exceptional stability in the temperature range of 650 to 1040°C and is suitable for applications in highly corrosive atmospheres.

Key Features

• Excellent Structural Stability: Especially effective in resisting corrosion in the heat-affected zones at high temperatures.
• Strong Corrosion Resistance: Outstanding resistance to high-temperature mineral acids, chlorides, acetic acid, seawater, and other corrosive media.
• Good Weldability: Can be directly used after welding, ensuring structural integrity and stability.
• High-Temperature Stress Corrosion Crack Resistance: Effective in resisting stress corrosion cracking in oxidizing environments.

Applications

• Flue Gas Desulfurization Systems
• Pickling and Acid Regeneration Plants
• Acetic Acid and Agricultural Chemical Production
• Titanium Dioxide Production (Chloride Process)
• Electrolytic Plating Equipment
• Corrosive Media in Wet Chlorine, Hypochlorite, Hydrochloric Acid, and Chloride Systems
• Seawater and Saltwater Solutions
