Hastelloy C276 - Nickel-Chromium-Molybdenum Superalloy Plate

Hastelloy C276 Plate: Performance Characteristics and Applications
1. Performance Characteristics
1.1 Excellent Corrosion Resistance
Hastelloy C276 plate exhibits exceptional corrosion resistance in both oxidizing and reducing environments, particularly against wet chlorine, chloride solutions, sulfuric acid, and acidic salt media. Its high molybdenum (15%-17%) and chromium (14.5%-16.5%) content effectively inhibits pitting and crevice corrosion, making it suitable for environments with high chloride concentrations.

1.2 High-Temperature Stability
This alloy maintains its mechanical properties at high temperatures, with operating temperatures exceeding 1000°C. The addition of tungsten enhances its high-temperature strength and oxidation resistance, making it stable in high-temperature equipment such as heat exchangers and reactors.

1.3 Excellent Mechanical Properties
With a tensile strength of 690-895 MPa and an elongation exceeding 40%, it combines high strength with good ductility. Its face-centered cubic crystal structure makes it nearly non-magnetic, making it suitable for manufacturing precision components.

1.4 Machining and Welding Characteristics
Although machining is challenging, cutting and welding can be achieved through specialized processes. Heat input must be controlled during welding to avoid sensitization; TIG or MIG processes are recommended.

2. Main Applications
2.1 Chemical and Petrochemical Industries
Used in the manufacture of equipment such as reactors, storage tanks, and heat exchangers, offering corrosion resistance to strong acids, alkalis, and chloride solutions, extending equipment life.

2.2 Flue Gas Desulfurization Systems
In wet flue gas desulfurization units, it resists corrosive gases such as sulfur dioxide and hydrogen chloride, ensuring long-term operation of environmentally friendly equipment.

2.3 Marine and Energy Engineering
Suitable for seawater desalination equipment and offshore oil platform pipelines, offering resistance to seawater corrosion and high-pressure environments, reducing maintenance costs.

2.4 Aerospace and Nuclear Energy
Used in the manufacture of engine components, gas turbine blades, and nuclear reactor components, meeting the requirements of high-temperature, high-stress, and radiation environments.

2.5 Pharmaceutical and Papermaking Industries
It resists organic solvent corrosion in pharmaceutical equipment and is used for bleaching containers in the papermaking industry, ensuring production safety and efficiency.

Hastelloy C276 sheet, due to its comprehensive properties, is an ideal material for use in extremely corrosive environments and is widely used in various industrial fields.
