Stainless Steel 347 Stud Bolts is a high-temperature, corrosion-resistant alloy that is commonly used in applications where elevated temperatures are a concern. Stainless Steel 347 stud bolts are fasteners specifically made from this alloy. Here are some key features, applications, and heat treatment information for Stainless Steel 347 stud bolts:
Features:
Corrosion Resistance: Stainless Steel 347 contains chromium and nickel, which provide excellent corrosion resistance, especially in environments with acids, alkalis, and high-temperature oxidizing conditions.
High-Temperature Resistance: This alloy can withstand elevated temperatures, making it suitable for applications in heat exchangers, furnace components, and other high-temperature environments.
Strength and Durability: Stainless Steel 347 stud bolts offer good mechanical properties, including high tensile strength and resistance to creep and stress rupture.
Weldability: It can be readily welded using standard welding techniques, which is important for applications where custom fastener lengths or configurations are required.
Stability: Stainless Steel 347 is stabilized with niobium (columbium), which prevents intergranular corrosion after exposure to high temperatures.
