Hastelloy C-276 Product Options

Hastelloy C-276 wire mesh is predominantly used in filtration and separation processes within chemical processing plants. The alloy’s remarkable resistance to a broad spectrum of corrosive chemicals, including chlorides and sulfides, ensures the integrity and longevity of filtration systems even under harsh conditions. This makes Hastelloy C276 wire mesh an ideal choice for applications such as acid filtration and catalyst recovery. Additionally, its ability to withstand high temperatures without compromising performance further enhances its applicability in high-temperature chemical reactions and heat exchange processes.

Hastelloy C-276 perforated metal offers a combination of strength, durability, and corrosion resistance, which is essential in industries like petrochemical and oil and gas. This form is commonly used in applications requiring controlled ventilation or fluid flow, such as in heat exchangers, where the alloy’s resistance to both oxidizing and reducing environments is crucial. The perforated metal is also utilized in acoustic applications due to its robustness and ability to endure corrosive environments, making it suitable for soundproofing in industrial settings where chemical exposure is prevalent.

Hastelloy C-276 expanded metal provides a versatile solution for applications requiring a high strength-to-weight ratio and excellent permeability. This makes it ideal for use in walkways, platforms, and fencing within chemical processing plants and offshore oil rigs, where exposure to corrosive substances is frequent. The expanded metal’s open structure ensures effective ventilation while maintaining safety and stability, qualities essential for environments where slip resistance and load-bearing capacity are critical.

Hastelloy C-276 bar grating is engineered for heavy-duty applications, offering superior load support and durability. This form is extensively used in industrial flooring, stair treads, and catwalks in environments such as refineries and marine facilities, where the alloy’s resistance to both seawater and aggressive industrial chemicals is vital. The grating’s open grid design allows for drainage and airflow, reducing the risks of hazardous liquid accumulation while providing a safe, non-slip surface.

The use of Hastelloy C-276 Alloy in these forms ensures enhanced safety, efficiency, and reliability across various industries, enabling operations to maintain high standards of performance and durability in some of the most challenging industrial environments.

Alloy C-276

Principal Design Features: C-276 is a wrought corrosion-resistant alloy. A prime advantage of this alloy is that it generally does not require solution heat treatment after welding. It resists the formation of grain boundary precipitates that would degrade corrosion resistance.

Partial List of Applications: Chemical process equipment and desulfurization of flue gas equipment.

Machinability: Good machinability, although the alloy work hardens as is true of the nickel base alloys in general.

Forming: Can be cold worked by all conventional methods.

Welding: Weldable by all common methods except that excessive heat input should be avoided. Can be used in the “as-welded” condition without further heat treatment for most corrosive applications.
