Chemical Composition: Stainless Steel 347H is an austenitic stainless steel alloy that contains high levels of chromium (about 18-20%), nickel (about 9-13%), and small amounts of other elements such as carbon, manganese, and silicon. The addition of niobium (columbium) further enhances its performance by stabilizing the material against sensitization and intergranular corrosion.
Corrosion Resistance: Stainless Steel 347H exhibits remarkable resistance to corrosion, particularly in environments where acids, alkalis, and chloride-containing substances are present. This property makes it ideal for use in chemical processing, petrochemical, and offshore industries.
High-Temperature Strength: With a maximum operating temperature of up to 1600°F (870°C), Stainless Steel 347H maintains its structural integrity and mechanical properties even in extreme heat. It is commonly used in applications involving heat exchangers, furnaces, and high-temperature processing equipment.
Excellent Weldability: Stainless Steel 347H is highly weldable, allowing for ease of fabrication and installation. This attribute makes it a cost-effective choice for complex piping systems.
Creep Resistance: Its resistance to creep deformation under high stress and temperature conditions is another notable advantage. This property is vital in applications where pipes are subjected to prolonged stress at elevated temperatures.
Durability: Stainless Steel 347H is known for its long service life, reducing maintenance costs and downtime.
