DESCRIPTION

Alloy 200 is an unalloyed wrought nickel. It offers excellent corrosion resistance, good mechanical, magnetic and magnetostrictive properties and useful thermal and electrical conductivities.

DESIGN FEATURES

• Excellent resistance to many corrosive media from acid to alkaline.
• Extremely high resistance to caustic alkalis including the molten state.
• Resistance to mineral acids varies according to temperature and concentration and whether or not the solution is aerated. Corrosion resistance is better in non-aerated acids.
• In acid, alkaline and neutral salt solutions, Alloy 200 shows good resistance, however, severe attack occurs in oxidizing salt solutions.
• Resistant to all dry gases at room temperature.

TYPICAL APPLICATIONS

• Food production, such as the handling of cool brines, fatty acids and fruit juices
• Vessels in which fluorine is generated and reacted with hydrocarbons
• Storing and transportation of phenol - immunity from any form of attack ensures absolute product purity
• Manufacture and handling of sodium hydroxide, particularly at temperatures above 570oF
• Production of viscose rayon and manufacture of soap - general corrosion resistance and virtual immunity to intergranular attack above 600oF
• Production of hydrochloride and chlorination of hydrocarbons such as benzene, methane and ethane

GENERAL MECHANICAL REQUIREMENTS

KSI can be converted to MPA (Megapascals) by multiplying by 6.895.

J&J stocks Alloy 200 dual certified to Alloy 201 with reduced carbon content (0.02% MAX) for better corrosion resistance at temperatures above 570oF by avoiding graphite precipitation.
