347 stainless steel is a stabilized austenitic stainless steel that contains niobium, which helps to prevent intergranular corrosion that can occur during welding and exposure to high temperatures. It is often used in high-temperature applications due to its excellent resistance to oxidation and its ability to withstand high temperatures without losing its strength or corrosion resistance properties. Some of the key properties of 347 stainless steel include: High-temperature resistance: 347 can withstand high temperatures up to 870Ã?Â°C (1600Ã?Â°F) without losing its strength or corrosion resistance properties, making it ideal for use in high-temperature applications such as furnace parts and exhaust systems. Corrosion resistance: 347 offers excellent resistance to corrosion, including aqueous corrosion and stress corrosion cracking. Weldability: 347 is easily weldable using common welding techniques, and the addition of niobium helps to prevent intergranular corrosion that can occur during welding. Strength and toughness: 347 has good strength and toughness, making it suitable for use in demanding applications. Some of the common applications for 347 stainless steel include: High-temperature furnace parts, such as burners and heating elements Exhaust systems in automobiles, aircraft, and industrial equipment Chemical processing equipment Jet engine parts Heat exchangers Overall, 347 stainless steel is a highly reliable and versatile material that is well-suited for use in high-temperature applications where superior corrosion resistance and strength are required, and where welding is required. The following are some of the commonly used international standards for 347 stainless steel: ASTM A240/A240M: Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications ASTM A276/A276M: Standard Specification for Stainless Steel Bars and Shapes EN 10088-2: Stainless steels - Part 2: Technical delivery conditions for sheet/plate and strip of corrosion resisting steels for general purposes EN 10095: Heat resisting steels and nickel alloys JIS G4304: Hot-rolled stainless steel plate, sheet and strip JIS G4305: Cold-rolled stainless steel plate, sheet and strip GB/T 4237: Hot rolled stainless steel plate, sheet and strip GB/T 3280: Cold rolled stainless steel plate, sheet and strip We can provide the following form:347 stainless steel coil; 347 stainless stee strip;347 stainless stee plate; 347 stainless steel sheets; 347 stainless steel tubes; 347 stainless steel pipe; 347 stainless steel flat; 347 stainless steel bar Widely used in boiler, power generation, petroleum, chemical, synthetic fiber, food, paper and other industries.
