Corrosion-Resistant C276 Alloy Strip for Aerospace & Chemical Processing

Introduction

Hastelloy C276, a nickel-chromium-molybdenum tungsten alloy, is universally recognized as a premier solution for combating severe corrosion in demanding environments. Its exceptional resistance to a wide spectrum of corrosive media makes it an indispensable material for critical applications in the aerospace and chemical processing industries (CPI). This product information sheet details the properties, specifications, and applications of our precision-manufactured C276 alloy strip, engineered to meet the most stringent quality and performance standards.

Key Characteristics and Advantages

The outstanding performance of Hastelloy C276 stems from its carefully balanced chemical composition, which provides a unique combination of properties:

• Exceptional Corrosion Resistance: This is its defining feature. C276 exhibits excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. It handles oxidizing and reducing agents with ease, making it highly effective in environments containing chlorides, sulfuric acid, hydrochloric acid, phosphoric acid, and other aggressive chemicals.

• Versatility: Its wide-ranging corrosion resistance eliminates the need for multiple specialized alloys, simplifying inventory and design choices for equipment that faces varied chemical exposures.

• High Strength: It maintains excellent mechanical properties at both elevated temperatures (up to approximately 1000°C / 1832°F) and cryogenic temperatures, ensuring structural integrity under extreme conditions.

• Fabrication Friendly: Despite its high strength, C276 strip can be readily fabricated and formed using standard techniques, allowing for the production of complex components like springs, seals, and diaphragms.

Chemical Composition (Typical % Weight)

Note: Low carbon and silicon content is crucial for minimizing carbide precipitation during welding, which preserves corrosion resistance in the heat-affected zone (HAZ).

Applications in Aerospace & Chemical Processing

The unique properties of C276 strip make it the material of choice for numerous high-stakes applications.

Aerospace:

• Engine Components: Used for seals, shrouds, and containment rings where exposure to high temperatures and corrosive combustion by-products is a concern.

• Fasteners and Springs: Critical for its high strength-to-weight ratio and resistance to atmospheric and chemical corrosion.

• Exhaust Systems: Components in auxiliary power units (APUs) and other systems requiring heat and corrosion resistance.

Chemical Processing & Petrochemical:

• Pollution Control: Fabricated into strip for flue gas desulfurization (FGD) systems, handling wet chlorine gas and chlorinated salts.

• Reactor Components: Used for catalyst grids, liners, and baffles in reactors processing aggressive acids.

• Gaskets & Seals: Precision-formed into C-rings and other seals for pumps, valves, and vessels handling corrosive media.

• Heat Exchangers: Strip can be fabricated into parts for heat exchangers in acid service.
