Stainless Steel 347 Nuts

What is Stainless Steel 347 Nuts?

Stainless Steel 347 Nuts are made from a stabilized austenitic stainless steel alloy containing columbium (niobium), which enhances their resistance to intergranular corrosion after exposure to high temperatures. These nuts are designed for use in applications where high heat resistance and oxidation stability are crucial. They maintain excellent mechanical properties and corrosion resistance in oxidizing environments up to 870°C (1600°F).

Applications of Stainless Steel 347 Nuts

Heat Exchangers – Commonly used in high-temperature chemical and petrochemical systems.
Aerospace – Applied in engine components and exhaust systems.
Power Generation – Used in boiler casings, furnace parts, and turbine components.
Chemical Processing – Suitable for nitric acid and oxidizing environments.
Marine Industry – Excellent corrosion resistance in seawater-exposed systems.
Oil & Gas – Used in refining and high-temperature drilling environments.

Common Uses of Stainless Steel 347 Nuts

Used in flanges, valves, and fittings operating under heat stress.
Employed in heat-resistant machinery and structural assemblies.
Ideal for furnace parts and exhaust manifolds.
Used in power plants for high-pressure, high-temperature joints.
Applied in industrial equipment and chemical reactors.
Used in refineries and heat treatment equipment requiring long-term stability.
