Hastelloy C-4 square plate
Hastelloy C-4 square plate is a nickel-based superalloy square plate. It is made by precision rolling and heat treatment. It has standard sizes, like thickness from 5 mm to 50 mm and side length up to 2000 mm. It also has strict tolerance control.
Hastelloy C-4 square plate mainly contains nickel. It has 16% chromium and 16% molybdenum. It also has small amounts of titanium and iron. It has a low carbon design with carbon content of less than or equal to 0.015%. It is stabilized to improve its resistance to sensitization.
Hastelloy C-4 square plate is widely used in many fields. In the chemical industry, it is used in reactors and acid treatment equipment. In the environmental field, it is used in flue gas desulfurization systems. In the aerospace industry, it is used in high-temperature parts.
Hastelloy C-4 square plate has excellent corrosion resistance, thermal stability, and weldability. It is an ideal material for extreme corrosive and high-temperature environments. It ensures the long life and safe operation of equipment.
Features of Hastelloy C-4 square plate
Excellent Corrosion Resistance: Hastelloy C-4 square plate performs well in both oxidizing and reducing environments. It is especially resistant to hydrochloric acid, sulfuric acid, and chloride stress corrosion cracking (SCC). It can withstand temperatures above 1000℃.
Thermal Stability: With a low thermal expansion coefficient and high-temperature strength (usable up to 650℃ continuously), Hastelloy C-4 square plate is suitable for thermal cycling environments.
Workability and Weldability: After solution strengthening treatment, the plate has good ductility. It can be cold-formed and welded (such as TIG welding and laser welding). It is also resistant to intergranular corrosion after welding.
Applications of Hastelloy C-4 square plate
Chemical Industry: Hastelloy C-4 square plate is used to make reactors, heat exchangers, and piping systems. It deals with acidic media (like in phosphoric acid production).
Environmental and Energy: Hastelloy C-4 square plate is used in components of flue gas desulfurization (FGD) systems, such as scrubber towers. It resists corrosion from wet sulfur-containing gases.
Aerospace: Hastelloy C-4 square plate is used for high-temperature gas path liners. It meets the requirements for lightweight and heat resistance.
