Хастеллой C4 solves the problem that standard трубы из нержавеющей стали а также фитинги из нержавеющей стали often lack the durability needed in коррозионные среды. Known for its stability, it also offers corrosion resistance.
What is Hastelloy C4 | UNS N06455
Hastelloy C4 is a nickel-chromium-molybdenum alloy that belongs to the Hastelloy family. It is a solid solution alloy, meaning that it cannot be age-hardened. The very low carbon content, combined with its special composition, makes it very stable and resistant to sensitization.
Key Advantages of Hastelloy
Hastelloy C4 is resistant to a wide range of corrosive media, with both oxidizing and reducing environments, as well as коррозионное растрескивание под напряжением.
It is very stable at high temperatures and prevents sensitization. This means that its corrosion resistance remains after welding.
Hastelloy C4 is easy to weld and easy to form. This ensures that complex welding and fabrication processes can be simplified.
Hastelloy C4 excels in many industries, including chemical processing, pollution control and food processing.

Hastelloy C4 in High Pressure Piping Systems
- Chemical Processing: Used in highly corrosive environments, it handles strong acids and chlorides as well as aggressive pesticides and fertilizers.
- Pollution Control: To withstand highly corrosive acidic condensates in flue gas desulphurization systems.
- High Temperature Systems: Shafts, valves and fasteners for use at high temperatures.
- Piping Systems: Critical fittings in piping systems require extreme corrosion resistance to ensure system integrity.
Sourcing and Fabricating Hastelloy C4
A complete Отчет об испытаниях материала (MTR) is required. It verifies the precise composition of the alloy and ensures its performance.
Работа с specialized suppliers of stainless steel pipe and fittings. They understand these alloy steels and can ensure proper fabrication and quality control,and are ISO 9001 и CE-PED certified.
This alloy requires specific procedures. Proper welding technique ensures the integrity of the weld.
It is expensive, so it is important to assess whether the product has a longer service life. This can justify its higher initial cost.
